If you’ve been getting the error COM Surrogate has stopped working whenever you browse folders containing video or media files, you have come to a good place for some possible solutions. This problem is caused because of codecs and other COM components installed by various softwares that aren’t fully Vista-compatible, like some versions of DivX or Nero.
Here’s the error message:
There are a number of possible solutions to this problem, and the right solution depends greatly on what software is actually causing the problem. Some of the most well-known problem causing softwares are DivX and Nero, but there are others that cause the problem as well.
- If you are using DivX, you should be upgraded to the very latest version (6.5+)
- If you are using Nero, you can try upgrading to the latest version (18.104.22.168+)
- If you’ve upgraded Nero and Divx and still have the problem, you can try renaming the file C:\Program Files\Common Files\Ahead\DSFilter\NeVideo.ax to NeVideo.ax.bak. You may also need to rename NeVideoHD.ax to NeVideoHD.bak
This will break Nero Showtime, however. (thanks to dugi in the comments for this one)
- You can disable Thumbnail previews, which should make the problem go away, but isn’t the optimal solution.
- The older ffdshow codec pack has been known to cause some problems. The ffdshow tryouts codec pack seems to work better. Might want to try using this one: http://ffdshow-tryout.sourceforge.net/
- If you’d like to uninstall Nero entirely, there is a utility that they provide to help with complete uninstall that helps a lot in instances where you have a bad installation of an older version. http://www.nero.com/nero7/eng/FAQs_Nero7_NeroVision.html
- Some users have recommended installing the Vista Codec Package in order to update all your codecs to the correct versions. I can’t confirm that this works because I have not tried it myself. As always, be careful when installing unknown components and create a restore point.
- You can use the very useful MMCompView free utility from Nirsoft to disable any codecs on the system. This is very useful to help troubleshoot exactly which component is causing the problem.
- There’s another possible solution below of turning off DEP for dllhost, which might not work for everybody. You may have to add divx+nero executables to the DEP ignore list.
Alan McC wrote in with this fix that might solve the problem in a much easier way. Essentially, turning off Data Execution Prevention on dllhost (the COM surrogate) can fix this problem for some people. This solution is detailed below.
Right click on Computer, and choose Properties
Click on Advanced System Settings, and then under Advanced, click Settings
Select the “Data Execution Protection” tab, and then click “Turn on DEP for all programs and services except those I select
