Some customers are having trouble in installing my msi package.
The error message says 'This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package'.
The customers' PCs are Windows 7, 64-bit. This same trouble repeated in several PCs of his.
But I have the same OS and PC settings, everything was fine.
One of the internet articles suggest that the Windows Installer service might be disabled.
Then some articles suggest that it was a privilege issue but then some people said that they still have the same issues despite having administrative right.
Could someone point to me the right direction please. thanks.
