As the program executable name has 'update' in its filename, gtk4-update-icon-cache.exe is considered to be an installer program on 32-bit Windows [1], which will cause the program to fail to run unless it is running with elevated privileges (i.e. UAC). Avoid this situation by embedding a manifest file into the final executable that tells Windows that this is not a program that requires elevation. Fixes issue #3632.
