FindProc not finding process

I thought that it might be case sensitive too, but when I look at the process list it says Game.exe, which is what I'm looking for. I've also tried game.exe, but that didn't work either.

Here is what I'm doing now:

   CheckRunning:
      Sleep 1000
      FindProcDLL::FindProc "Game.exe" 
      StrCmp $R0 "1" CheckRunning

It used to be:

      CheckRunning:
            Sleep 1000
            FindProcDLL::FindProc "$APPEXE"                  
            StrCmp $R0 "1" CheckRunning

but for some reason the program's launch executable launches another program then closes.
