Can't reinstall Ghost 15 on Win 7

I updated Vista to Win 7 and GHOST 15 somehow got messed up. Repair would not work so I installed and got everything, or so I thought.  When I try to reinstall I get an error that a newer version is already installed, 15.01.xxxxxxx.  Please uninstalled and try again.  I guess my install CD is something older than that but it is at least 15.0.

 

I cannot find anything to uninstall, no folders or registry keys and nothing in add remove.

 

How do I get around this?????
