Fix Problems Upgrading Office 2010 Beta to RTM (Final) Release

There are several scenarios where you may run into trouble uninstalling the 2010 Beta and trying to install the RTM (final) release. Today we’ll cover the problems we ran into, and how to fix them.

You would think upgrading from the Office 2010 Beta to the final release would be an easy process. Unfortunately, it’s not always that simple. In fact, we ran into three different scenarios where the install wasn’t smooth whatsoever.

If you currently have the 2010 Beta installed, you have to remove it before you can install the RTM.  Here we’ll take a look at three different troublesome install scenarios we ran into, and how we fixed each one.


Important Note: Before proceeding with any of these steps, make sure and backup your Outlook .pst files!

Scenario 1 – Uninstall Office 2010 Beta & Fix Install Errors

In this first scenario we have Office Professional Plus 2010 Beta 32-bit installed on a Windows 7 Home Premium 32-bit system.

First try to uninstall the Office 2010 Beta by going into Control Panel and selecting Programs and Features.


Scroll down to Microsoft Office Professional Plus 2010, right-click it and select Uninstall.


Click Yes when the confirmation dialog box comes up.


Wait while Office 2010 Beta uninstalls…the amount of time it takes will vary from system to system.


To complete the uninstall process, a reboot is required.


Fixing Setup Errors

The problem is when you start the installation of the 2010 RTM…


You get the following setup error even though you uninstalled the 2010 Beta. The problem is there are leftover Office apps or stand alone Office products. So, we need a utility that will clean them up for us.


Windows Installer Clean Up Utility

Download and install the Clean Up Utility (link Below) following the defaults.


After it’s installed you’ll find it in Start \ All Programs \ Windows Install Clean Up …go ahead and launch the utility.


Now go through and remove all Office Programs or addins that you find in the list. Make sure you are just deleting Office apps and not something you need like Java for example. If you’re not sure what something is, doing a quick Google search should help you out. For instance we had the Office labs Ribbon Hero installed… just highlight and click Remove.


Remove anything that has something to do with Office…then reboot your machine.


Now, you should be able to begin the installation of Office 2010 RTM (Final) Release without any errors.


If you do get an error during the install process, like this one telling us we have old version of Groove Server…


Navigate to C:\Users\username\AppData\Local\Microsoft (where username is the computer name) and delete any existing MS Office folders. Then try the install again, this solved the problem in our first scenario.


Scenario 2 – Not Being Able to Uninstall 2010 Beta from Programs and Features

In this next scenario we have Office Professional Plus 2010 Beta 32-bit installed on a Windows 7 Home Premium 32-bit system.

Another problem we ran into is not being able to uninstall the 2010 Beta from Programs and Features. When you go in to uninstall it, nothing happens.


If you run into this problem, we again need to download and install the Windows Installer Clean Up Utility (link below) and manually uninstall the Beta. When you launch it, scroll down to Microsoft Office Professional Plus 2010 (Beta), highlight it and click Remove.


Click OK to the Warning Dialog box…


If you see any other Office 2010, 2007, or 2003 entries you can hold the “Shift” key and highlight them all…then click Remove and click OK to the warning dialog.


Now we need to delete some Registry settings. Click on Start and type regedit into the Search box and hit Enter.


Navigate to HKEY_CURRENT_USER \ Software \ Microsoft \ Office and delete the folder.


Then navigate to HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Office and delete those keys as well.


Now go into C:\Program Files and find any of these three folders…Microsoft Office, OfficeUpdate, or OfficeUpdate14…you might find one, two or all three. Either way just rename the folders with “_OLD” (without quotes) at the end.


Then go into C:\Users\username\AppData\Local\Microsoft and delete any existing MS Office folders. Where in this example we have office, Office Labs, One Note…etc.


Now we want to delete the contents of the Temp folder. Click on Start and type %temp% into the Search box and hit Enter.


Use the key combination “Ctrl+A” to select all the files in this folder, then right-click and click Delete, or simply hit the Delete key.


If you have some files that won’t delete, just skip them as they shouldn’t affect the Office install. Then empty the Recycle Bin and restart your machine.


When you get back from the restart launch the Office 2010 RTM installer and you should be good to go with installation.


Because we uninstalled the Office 2010 Beta manually, you may have some lingering blank icons that you’ll need to clean up.


Scenario –3 Uninstall 2007 and Install 2010 32-Bit on x64 Windows 7

For this final scenario we are uninstalling Office Professional 2007 and installing Office Professional Plus 2010 32-Bit edition on a Windows Ultimate 64-bit computer. This machine actually had Office 2010 Beta 64-bit installed at one point also, it’s since been removed, and 2007 was reinstalled. 

Go into Programs and Settings and uninstall Microsoft Office Professional 2007.


Click Yes to the dialog box asking if you’re sure you want to uninstall it…


Then wait while Office 2007 is uninstalled. The amount of time it takes will vary between systems.


A restart is required to complete the process…


Again we need to call upon the Windows Installer Clean Up Utility. Go through and delete any left over Office 2007 and 2010 entries.


Click OK to the warning dialog that comes up.


After that’s complete, navigate to HKEY_CURRENT_USER \ Software \ Microsoft \ Office and delete the folder.


Then navigate to HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Office and delete those keys as well.


We still need to go into C:\Users\ username\AppData\ Local\ Microsoft (where username is the computer name) and delete any Office folders. In this example we have Outlook Connector, Office, and Outlook to delete.


Now let’s delete the contents of the Temp folder by typing %temp% into the Search box in the Start Menu.


Then delete all of the files and folders in the Temp directory.


If you have some files that won’t delete, just skip them as they shouldn’t affect the Office install. Then empty the Recycle Bin and restart your machine.


If you try to install the 2010 RTM at this point you might be able to begin the install, but may get the following Error 1402 message.


To solve this issue, we opened the command prompt and ran the following:

secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose


After the command completes, kick off the Office 2010 (Final) RTM 32-bit edition. This solved the issue and Office 2010 installed successfully.



Except for the final scenario, we found using the Windows Installer Clean Up Utility to come in very handy. Using that along with deleting a couple folders and registry settings did the trick. In the last one, we had to get a bit more geeky and use some command line magic, but it got the job done.

After some extensive testing in our labs, the only time the upgrade to the RTM went smoothly was when we had a clean Vista or Windows 7 system with a fresh install of the 2010 beta only. However, chances are you went from 2003 or 2007 to the free 2010 Beta. You might also have addins or other Office products installed, so there are going to be a lot of different office files scattered throughout your PC. If that’s the case, you may run into the issues we covered here.

These are a few scenarios where we got errors and were not able to install Office 2010 after removing the beta. There could be other problems, and if any of you have experienced different issues or have more good suggestions, leave a comment and let us know!

    You did not mention one problem that occurred during the installation.
    I did not have any problem uninstalling and then installing as you indicate might happen to some, but when I tried to change the options in Outlook and save them, it always would tell me that it could not find the file. (Of course it did not tell me which file or give me any details.)

    My solution was to start Outlook in Safe mode, save the options, and then go back to starting Outlook normally and the save now worked. I am using the 32 bit version.

    the office 2007’s uninstall procedure was also poorly written(i believe), most of the time had to go use the windows installer cleanup program to uninstall it, the problem persists in office 2010 beta, hope office 2010 RTM’s uninstaller does what its supposed to do

    I’ve been so happy with the 2007 version of Office that I didn’t download the 2010 beta. Now, I’m waiting for the discounted version that is made available to people with a college email address (hey, it pays to have kids sometimes!).

    Because I haven’t yet tried 2010, I wonder if you could answer a question. Does Word 2010 have the ability to save documents as EPUB files so I can transfer them to my Nook ereader? (Yes, I could do it as PDF, but it is nowhere near as nice on an ereader screen.) I looked for the answer online, but couldn’t find it mentioned anywhere. Apparently one of the open-source word processors allows for this, so I’m hoping that Word will, too.

    If anyone is able to answer this, I really appreciate it. If not, hopefully I’ll be happily surprised when I buy it soon.

    Great article, I just installed 2010 this weekend and I was fortunate that it went alright. But I have 3 to go…

    I’ve just upgraded from the 2010 Beta to the RTM. I uninstalled using Revo Uninstaller, and had no problems upgrading at all.

  6. Derek Iannelli-Smith

    This would have been helpful a month ago when I was uninstalling Office 2010 and going back to 2007 due to an incompatibility with a business essential plugin. How I got office 2010 totally cleaned off without having to use the Microsoft Utility was RevoUninstaller…. no garbage left behind. Thanks for the great reminders though and tools… appreciate your hardwork.

  7. ronnieg

    I used a third party uninstaller for my 2010 Beta. It took out everything. I then installed RTM without any problems. I did make a copy of my pst file but when I ran Outlook 2010 for the first time it had all my info, address book and all in it already.

  8. matej

    I’m not succesfull while installing office 2010. I have removed beta version as describedl. I’ve started RTM install without any problem, but installer didnt finished. I didn’t get any error, progress bar was on 100% but never finished. I don’t know what else can I do.

  9. Henry Werch

    I had a similar problem with my install of Office 2010 RTM after I uninstalled the Beta, but in my case it installed but 2010 only opened in “Compatability Mode” and certain features weren’t accessable. Not being a “geek” myself, It took a 1 1/2 houjr session with Support to delete the remnants of 2007 from the registry that caused the problem. So, geeks, look to the registry first if you are still having problems!

  10. Spyvila

    When I install office 2010 it is working. And office 2007 is also working. After restart the computer it is not open only one circle is come with mouse then there no screen has been come. What is exact problem? I Need to install again?

  11. Doug

    I had to use this MS KB fix to get Office 2010 Pro installed after it failed to install complaining about “upgrading from a prerelease version”, the 2010 beta I has tried a few months ago. I tried all the steps listed in the article above with no joy. This KB article was tough with lots of reg manual reg editing, but it worked for me. I also uninstalled my MS Live Mesh at the same time, so I am not sure which was the critical corrective action. I spent about 5 hrs working on the simplier approaches, but they did not work for me.

    KB article: How to manually uninstall the 2007 Office system if you cannot uninstall it by using the “Add or Remove Programs” feature

    Good luck,

    I had to remove ms project 2010 demo on another computer to get office 2010 successfully installed.

    Thanks, Mystikgeek! I went from 2007 to 2010Beta running Windows 7. My uninstall, clean-up w/ MS FixItForMe, and clean re-install went incredibly smoothly because of your help! Thanks for making my day!

  22. Kunle

    Thanks for this, it worked quite well for me and very straightforward.

  23. Adrienne

    I am about to switch from the beta to the final version of office 2010, will I loose all my biography info from the beta version?

  24. Tiffany M

    I upgraded to final, but can’t find a way to get all of my pop email accounts and messages back. the backup .pst file is 2gb so it must be in there. Please help, I am stuck and have deadlines for business.

  25. David

    I have the final release of Office 2010 installed (also had problems installing it over the beta version) but now ok, however when I try and install Project 2010 I get the same error message that beta is still installed, I have tried the above fixes without any luck, any ideas?

  26. Benjamin Rau

    I hate to say it, but after reading all the horror stories, and printing out the suggestions, I just uninstalled the Beta, using the automatic uninstall from Control Panel, and then installed my downloaded Office. No trouble. When I started up Outlook (which was my real concern) I found all my accounts, and all my messages (actually too many) right where I left them. I have found no troubles at all. Except paying $499 for the Professional version.

  27. jhay080

    I followed everything that was suggested on this thread but it did not work. I have a Windows 7 32bit computer. Please help! Thank you.

  28. jhay080

    Hi David,

    Can you share to us what you did? Most probably I am experiencing what you had but you were able to fix it. Please?! Thanks

  29. txwylde

    I have a Masters Degree in CIS and have worked Tech Support for Citicorp and Dell. I can not get the Beta to go away. I followed these instructions to the letter and Office 2010 is still there. You try to uninstall it from Programs and the machine goes to reboot and then its still there. I have tried it in safe mode as well. Nothing works. I do not usually use my Windows 7 PC… normally run a Mac and have ZERO issues.

    What is the deal?

  30. Vivek

    please follow these step to resolve the this issue
    Please find the detailed step which I have followed.

    · Uninstall the MS office 2010 from Add/remove program and then Reinstall the Office 2010.
