Executing a custom action that requires elevation after install

Question

I have the following WiX snippet:

Answer 1

The UI sequence is running as a limited user, and it launches applications with a call to CreateProcess. If you use something like a WixShellExec with [WixShellExecTarget] instead, it will act like Explorer and show a UAC prompt if the target requires elevation. Or you could modify your Configurator.exe to allow being launched without elevated privileges, detect that case, and relaunch itself with elevated privileges.

For example, this should work:

  WIXUI_EXITDIALOGOPTIONALCHECKBOX = 1 and NOT Installed
