Script To Restart Application If Stopped

I have the following script on an XP computer and it successfully detects whether an application has stopped or is not responding. It kills if required and restarts. But it doesn't work on Windows 7. How can I either fix, or do the same thing another way on Windows 7? On XP if the app is not running then "%TEMP%TaskStatus.tmp.txt" ends up empty. On windows 7 it ends up with the string "INFO: ...." in it. So checking for size 0 doesn't work. I tried doing the same thing as done lower in the script but checking for Info: instead of SUCCESS: but it doesn't work for some reason.

Code:
@ECHO OFF
ECHO Restart Application
ECHO.
ECHO.
SETLOCAL EnableExtensions
[Code] .....
