Hi Derek, I think it's just a false report by Belarc and nothing to worry about. Why not use Windows 7 built in System Information reporter and see what that tells you. Hit the Start key and in the search box type, system information. Hit the Enter key then use the numeric keypad and half way down the screen it will tell you which operating system you have. I've got an Acer Inspire and mine reads. OS Name: Microsoft Windows 7 Home Premium.

My system is also Windows 7 SP1 and Belarc reports correctly. Suggest initially that you uninstall, re-boot system then download again and install. George.
