auto sandbox rule not working on one of my computers...

hi, I created a sandbox rule which runs perfectly on my laptop, but not on my desktop computer… I’ve formatted the hard drive, re installed windows 7, re installed CFW, and set up the sandbox rule… and still the file that is setup to be blocked is allowed to run… any ideas as to why CFW is broken on my desktop? how can I test CFW to be certain it is working as it should? can anyone please HELP…here is the initial post… oh, and no other AV or anti malware has been installed yet…
