i have windows XP professional. now every thing worked fine till MSOutlook gave me a msg "which i forget what is it" and if i pressed ok outlook closed, then i tried to reinstall office 2007, that didnt solve the problem. after that i did a system restore since my outlook was working fine 2 days ago.
outlook works again all other office product too, but every time i start office product the blue office window blinks "appear then disapear" many times after that windowsInstaller's window pops up with cancel button, after a minute it works fine no problem.
if then i closed the product same thing happened allover again.
i tried cleanup from microsoft, and checked my computer from viruses, its clean.
reinstalld many times even manually. nothing changed
