SOLVED – Windows Vista: Office 2007 installation runs every time I start Word or Excel, and Excel has an error about stdole32.tlb?

This is an annoying problem in Windows Vista that took me quite some time to fix. The problem is caused by incorrect registry permissions in Windows Vista, and this can affect not only the Office 2007 installation, but installations of any software. Problem in Office – the installation routine runs every time your start word or excel, and when starting Excel, a dialogue box pops up with just stdole32.tlb. Fortunately there is a fix.
