Hello,

I tried to format and print an old Caesar output file, using my new install of CAESAR II 2011. I received this error message:

"The selected file has an incompatable version number. Please run analysis again with the current version of Caesar II."

I know that the output data from the previous run exists in a readable form, and I do not want to make any changes; I just want to format and print a report. Can I do such a thing in CAESAR II 2011? How about if I had both 5.20 and 2011 installed? I have an updated USB HASP key, would that allow me to run both 5.20 and 2011?

There is new data in the 2011 (5.30) files, so the file structure changed. 2011 won't read output files created on any other version.

Yes you can have multiple versions fo CAESAR II installed on your machine. Your ESL will let your run both versions (we don't "stop" access to earlier versions).
