thank you for your solution.
know i am not so sure about the variable PRO_DIRECTORY.
i installed proe with default path, (PS:Windows 7, 64bit), i set PRO_DIRECTORY=C:\Program Files\proeWildfire 5.0\bin\

and whats more, now it always throwIpfcXToolkitCantModify, does it mean that i havent get anauthority?
