Thank you, I will try that. Only machine with the problm. While it shouldn't make any difference, the capitol letters were different in the two c:\temp locations Temp vs temp' . I have corrected that, uninstalled CC. Will try portable first and see what happens and then reinstall and test.
Do you know if CC uses the registry to find the Temp folders ? If it does, could be something there although everything is going to C:\ Temp the way I want.
