I am getting this error message when trying to install various apps… “Installation package could not be opened. Verify that the package exists and that you can access it, or contact vendor to verify that this is a valid Windows Installer package.”
I just got a new machine (new to me) Mainboard : Unspecified 8363-686A, Chipset : VIA KT133A , Processor : AMD Duron @ 900 MHz, Operating System : Microsoft Windows XP Professional 5.01.2600 Service Pack 2, however I was having the same problem with my other machine as well (asus board with intel PIII). I cannot install Java, Adobe, or even Windows Live Messenger, and this is on a fresh install. I found where it might be a bad Msi.dll file from the SP2 update, but don’t know how to fix it. Does anyone know of a work around or what is locking me out? HELP!
