Wix Custom Action during installation failing - windows

Question

I'm attempting to use a custom action to run a program with a command-line option during installation (after files copied). The action requires admin permission (it sets up and installs a windows service). For some reason, the custom action keeps failing.
My wix code:

This is the error I'm getting in the msi log:
MSI (s) (40:30) [22:58:07:647]: Created Custom Action Server with PID 11672 (0x2D98).
MSI (s) (40:40) [22:58:07:663]: Running as a service.
MSI (s) (40:40) [22:58:07:663]: Hello, I'm your 32bit Elevated custom action server.
CAQuietExec64: Error 0x80070002: Command failed to execute.
CAQuietExec64: Error 0x80070002: CAQuietExec64 Failed
CustomAction LaunchApplication returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
Action ended 22:58:07: InstallFinalize. Return value 3.
MSI (s) (40:D0) [22:58:07:694]: Note: 1: 2265 2: 3: -2147287035
If I run the command line as a normal user, it fails, but if I run it as an admin user (or the system user), it works. I'm fairly certain the problem is the permissions on the action. I've set it to deferred and Impersonate='no', but it's still not working. Anyone have any tips?
Edit: So, I've found that apparently shortcuts in launchapplication aren't working for the path of the executable. Does anyone know the syntax that allows for this?

Answer 1

Ended up figuring it out myself.
Changed the
<Property Id="LaunchApplication" Value=""MediaCollectorServerService.exe" -install"/>
line to
<SetProperty Id="LaunchApplication" Before="InstallInitialize" Sequence="execute" Value=""[#MediaCollectorServerService.exe]%quot; -install"><![CDATA[NOT Installed AND LaunchApplication=""]]</SetProperty>
Hoping this proves useful for others in the future.
