Hi, I don't know whats going on but I've tried to install ESET Nod 32 Antivirus Pkg. (and any other .msi pkgs) and I KEEP getting the following Windows error: Windows Installer "This Installation Package could not be opened. Verify that the pkg. existsand that you can access it, or contact the App. Vendor to verifythat this is a valid Win Installer Pkg." This happens in EVERY .msi pkg. I went to the Windows Support and Downloaded the Runtime Win Installer Pkg. BUT it keeps doing it! What is going on? Please help … Thanks
