I installed software for my HP Office Jet 4110v all in one. It said it could install it and everything passed inspection except the OS, Windows 7 Home Premium 64-bit. I installed it. After that, everything went to hell. I had to rename a couple of exe's for WinHlp.exe and HelpPane.exe to stop them from coming up. After that, I could access everything except the start menu and when I open any program now, the help application for that file automatically opens and cannot be closed or shut down.
I finally used the CD to uninstall the printer software that was not compatible with Windows 7 64-bit, but I still cannot get into the Start button menu (it tries to open but just flashes open for a millisecond then closes) and every program I open still opens its help application.
