Mirralph,
The programme not start in the manner you have described can have many causes.
Is this a new Windows 7 Professional installation or is it being used without problems with many other programmes ?
If it is not a new Windows 7 installation, then it is likely that there is conflict with something else running. The first thing I suggest you do is reboot the windows system and re-install the Configuration Tool without any other programme running and then try again.
