Excel automation stopped working

[phinds]

For no reason that I can tell, all of my programs that use Excel automation now give "automation error", with various large negative numbers as the error number.

I have re-installed both MS Office and Visual Studio (the "fix previous installation" re-install in both cases) to no avail.

Anyone have a clue what system file might need replacing?

Thanks

Are you automating on the server side? I am having this same trouble automating IE on the server side..... I found this http://support.microsoft.com/default.aspx?kbid=257757 the other day when searching to fix my IE automation. I haven't read it yet been too busy, but it might help. If you figure out your problem can you let me know, it may be the same fix for mine
