Hi. I noticed that despite having: <requestedExecutionLevel level="asInvoker" uiAccess="false"/>
in setup-x86_64.exe the UAC prompt is not bypassed and when I click Cancel the program is not started. Previously I used the same binary to install Cygwin for "Just me" on a host where regular users are simply not allowed to trigger a UAC prompt. I have downloaded some other software installers and they work as intended: cf7_installer.exe Git-2.33.0-64-bit.exe pgadmin4-5.6-x64.exe The following env var also failed: set __COMPAT_LAYER=RunAsInvoker Then I tried to un-UPX and remove the manifest with ResHacker and I also renamed "setup-x86_64.exe" to "putes-x86_64.exe" because I heard that UAC looks for keyword in .exe name without a manifest, but the resulting binary still triggers the UAC.
