#AutoIt3Wrapper_Run_Before command not working

I am using the following command:

#AutoIt3Wrapper_Run_Before=xcopy "%scriptdir%\Resources\*" "\\NetComp\docs\Resources" /s /i

When I compile, the console outputs this:

 

xcopy "C:\Sources\Resources\*" "\\NetComp\docs\Resources" /s /i 

When I run the command from a command prompt, it works without issue, but when I compile with autoit, nothing copies and no errors write to the console. Any idea what is going on?
