I have Vista Home Premium at SP1 and Office Home and Student 2007 installed (originally at SP1), recently I have started to get the following problem...

When I open an Excel spreadsheet I get a pop up with 'stdole32.tlb in it.
Once I OK it, Office then proceeds to Reconfigure Excel,
This happens every time I open an Excel spreadsheet ...

My understanding (from what I've read) is that the stdole32.tlb file is either missing or corrupt; I've checked my system and there is no such file.

I don't know when this problem manifested itself as I haven't used Excel for some time now, however I can say that Excel was working OK previously.

I have uninstalled and reinstalled Office a few times now and the problem still remains.

I have also run Office Diags a couple of times all to no avail !!

I'm assuming this file is something that is installed as part of the OS ...

Nothing I've read suggests how to recreate this file, is it possible ?
