Anyone can help with this @comspec syntax???

Hi guys,

I have this batch file that run the following code and it work fine.

C:\Windows\System32\cmd.exe /C set __COMPAT_LAYER=RunAsInvoker & start "" "C:\Program Files\test 123\test 123.exe"

but I'm trying to use autoit @comspec to compile it to a executable file. I'm having problem with the syntax. Can anyone be kind enough to guide me. This is the @comspec code I try.

RunWait(@Comspec & ' /c set __COMPAT_LAYER=RunAsInvoker ' & 'start' & 'C:\Program Files\test 123\test 123.exe')
