Looks to me like you are getting a path error... The proe "bin" folder must be in the path in order for thelicense borrowing script to run. In the past, Itypically did this by opening a cmd shell in the "bin" folder and running the "proe_borrow.bat" script. Seems that this is what you are doing, too?
Also it looks like you are running Windows 7 here - andmy comments are based on WinXP... I am just beginning to test Win7; and so far my observation is that Microsoft has made my life harder, not easier! 🙂 In XP, the current directory was assumed to be in the path. Perhaps this behavior is changed in Windows 7???
Try typing "path" in your command prompt & see what it looks like.
