Windows Installer not working for .msi installations.
Hi, I just upgrade my laptop (SONY VAIO VGN-SR430J) from Vista 64 bit to Windows 7 Home Premium 64 bit.
Everything seemed to be working normally until when I tried to install an antivirus (NOD32 Smart Security).
Its a .msi installer and when I tried to run it, it gave me an error "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package."
I googled this message and saw a few solutions but none of them had worked so far.
The first thing I did was download Windows Installer (WindowsInstaller-KB893803-v2-x86) and when I tried to run it, it says "Not enough storage is available to process this command."
Another post had also suggested to redownload the Windows update Agent and that did not do anything either.
Then I tried the solutions on this site. (Error message when you try to add or remove a program on a computer that is running Windows XP or Windows Server 2003: "The Windows Installer service could not be accessed").
Method 1 did not solve it and when I tried to do method 2, it keeps saying access denied in the cmd box even though I rightclicked and ran as admin.
Anyone got any other ideas?
I have alot of data on the laptop and I have been trying to avoid a complete installation.
