DEFENSE+ > Advanced > Computer Security Policy *CLICK*
Now scroll down in the "application name" list to the file called ((path) + "pp.exe")
Press EDIT.
Chose "Use a Custom Policy".
Next Click "Access Rights".
At "Run an executable" chose "default action = ASK".
And click at modify under settings, click blocked applications.
Click Add> Browse.. and find the cmd.exe file and add it here.
And under allowed applications chose add> File Groups > All Applications!
Should work now.

Hopefully.

EDIT:: didn't see EricJH's post, That way could be simpler! Anyway, hope you solve it.. If you already have a allow rule or deny rules for this "pp.exe" file you might however want to remove them first and then run the program in safe mode/paranoid mode.
