First of all Sir, bravo on this incredible sim. I can't wait to give it a go.
Are there installation issues with Windows 7 or Windows 8? Windows 7 I install it the furthest in compatibility for Windows Service Pack 3 and then I get an error that World004.dat can't be found. It's not a corrupt file issue, I've verified I downloaded all the files.
So I tried installing it on my Windows 8 system. No issues with the request for world004.dat. It appears to install all the files but then at the very end of the process it asks to insert a disc. ????? I was installing this under Windows Service Pack 3 compatibility as well.
