I recently bought a new HP computer and I am unable to run any MSI by double clicking it. I receive an error message:
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.
My account is an administrator account and I have disabled UAC. However, if I run a command line prompt as administrator and try to install the MSI package by using the below command, the software installs correctly without any error messages:
msiexec /package packagename.msi
Any ideas what could be causing this?
