Viewing old files
We have hundreds of old .prt files from the late 1980's that we cannot open or view.  We no longer use any form of CADkey so I downloaded KeyCreator Viewer.  When I try to open a file, I get an error stating 'unknown file type'.  Any suggestions?

RE:Viewing old files
The viewer can only read CadKey files newer than CadKey version 5. Anything older would need to be converted. 

If you can share a file and emailed it to support@kubotek3d.com, I can verify if this is indeed the issue.

RE:Viewing old files
Is there a place we can download older versions of the Spectrum viewer software?  I have an old installation that is looking for a missing *.msi file.
