Visual Studio 2008 - Unrecoverable Build Error

Using VS 2008, I just started getting this error for no apparent reason, after a few hours of frustration recreating the solution adding fresh web setup projects etc, I found this link.

suggested trying
"regsvr32 ole32.dll".

which did work...

Using the System Restore wizard I was reminded that yesterday I uninstalled SnagIt as the trial period had expired... putting SnagIt and ole32.dll into google brings me the SnagItGuide page telling me that back in March 2007 - "Fixed the bug where SnagIt removes ole32.dll registry keys." As I just got the SnagIt trial a month ago I guess the bug wasnt fixed to well after all.
