ERwin r7.3.x and r8.x can be installed on the same computer. How can I control which version of ERwin opens by default when I double click a .erwin file?
The last installed copy of ERwin will be the default version that launches on the PC where there are mixed versions installed. Each time you double click a .erwin model, that will launch the last installed version of ERwin as the default.
However, you can change the default version of ERwin that launches by modifying your path in the registry using Regedit. Here is the path for a Windows 7 machine:
Please change the default that is
"C:\Program Files (x86)\CA\ERwin Data Modeler r8\ERwin.exe" "%1"
"C:\Program Files (x86)\CA\ERwin Data Modeler r7.3\ERwin.exe" "%1"
to have ERwin r7.3 open the models instead.

Improper use of the Registry Editor can cause irreversible damage to your system!
If you are not familiar with—and completely comfortable with—the use of the Registry Editor, please seek assistance from your local IT support or contact erwin Technical Support for assistance.
