How do you open HYSYS version 8.2 in HYSYS 7.3. I have created a .xml file but it doenst seem to work.

Thanks,

This may be a version compatibility issues. Even AspenTech guys don't have a clear idea why it's not able to open. When I tried I got the following message "The file create in beta version of HYSYS and can't be open". my organization purchase the v8.3.
