Sometimes you might want to install an MSI on your Windows system, without being logged in as an administrator. Normally, you would just right click and select “Run as Administrator” but this option is not available on MSIs.
Instead, right click on “Command Prompt” in the start menu, then select “Run as Administrator”. Once this is running, use the msiexec command to execute the MSI.
msiexec /i Filename.msi
This will then run the installer using administrative privileges.
