Question:
Can I have versions 2.5, 3.0, and 3.1 of E3 running in the same computer?
Solution:
Yes. But you have to make sure there is no conflict between folder names and paths. Also, remember to always register the version via each version’s register.bat, in their respective Bin folders. Without this register, you will not be able to open a version other than the last one to be registered.
