Run Homesite on Windows 7

I’ve recently installed Windows 7 on my office computer and I’ve just realized that Homesite doesn’t run. I get an application error when Trying to open Homesite on Windows 7. The specific error is:

Application Error
Exception EOIeError in module homesite45.exe at 000803AC.
Error creating system registry entry.

Has anyone found a workaround to allow Homesite to run on Windows 7 without having to enter Windows XP mode? I’ve downloaded the XP mode that allows me to open Windows XP as a virtual terminal within Windows 7, but I’d prefer to run Homesite natively when opening it, rather than having to open a Windows XP terminal then having to open Homesite within that window.

If you’ve have any success, please comment below as Homesite has been a favorite for a long time.
