Error on Installing Cucusoft iPhone Tool Kit on Windows 7 (x64)

I have downloaded a full edition Cucusoft Apple iPhone Cock System using my Windows 7 (x64).
During the installation process, I have encountered a regedit issue.

After I saw this error, I shut down the entire software program and reopened it under "Process Administrator". I have already exhausted all troubleshooting steps possible for 3 times now and I still get the same error.
Is there any chance that I can correct this error?
Please send me the steps to do so.
