Hi Jason, thanks for responding. As it happens, I have copies of the program files (but not the installation disk) for AS, and the version for the Sketch.exe file appears to be 8.0.23.0 - so I'm guessing version 8? If I knew someone with the program installed, I would happily ask them to open one of these files just to be sure before we purchased the software.
We do not need to do anything other than view the files and possibly print to pdf.
