"This installation package could not be opened" only on AppVeyor

I'm trying to install an MSI file in the AppVeyor VM, but doing that fails with
"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 same file works fine on a Windows 7 box and doesn't produce such an error.
Are there any special things that you set up on the VM image maybe that could cause the error?

Thank you for your quick response.

Kind regards

    Hi Noel,

    Could you sent a link to an MSI you are trying to install (if it's public)?

    Also, here you can find a bunch of examples of how we do it when building an image: https://github.com/appveyor/build-images/tree/master/scripts/Windows

    Does that MSI support silent installation? You can peek into VM via RDP to see if there is some sort of error/crash/dialog.
