I am having this same issue "Microsoft Setup Bootstrapper has stopped working" error, and I see this only when trying to uninstall or install MS Office. Also, Windows Explorer keeps restarting.
Am able to install/uninstall other programs fine. It is just with the MS Office. I have seen in some other forums, that using a different CD/DVD drive might resolve the issue, but I just have a setup file that was downloaded from MS Website, and am bot using any Disc to install.
Somebody please help.
Thanks
Sandeep
