Failed to update the system registry

Hi guys, When I am installing FrontPage Express on my computer under Windows 7, I meet an error after rebooting my computer, the error message that I received Failed to update the system registry, please below the screen shot of the error message.
FrontPage Express
Failed to update the system registry
Please try using REGEDIT.
I am wondering why I get such error message, since I am using an administrator rights in installing FrontPage Express, my problem now is, what shall I do with the regedit command, I haven't use that command ever since, I am now asking for some guidance on what shall I do to finish my installation, thanks a lot.
