Can I stop an executable from requesting UAC elevation?

Question

I have an installer I'd like to run from a script. The installer requests UAC elevation but it doesn't need elevation because I'm installing to a user directory. Is there some way to run the installer so that it doesn't request UAC elevation?

The script is written in Python so I can access the Windows API through ctypes.

Changing the installer is not an option.

Answer 1

You have to set the enviromnet variable __compat_layer for your process to RunAsInvoker. Then you can run the executable without any UAC prompt.

You can use the Windows API function SetEnvironmentVariable for this purpose.
