Grem,
I would think that if you uninstalled EZ 2, ran a registry cleaner, and checked your
hard drive for "residue" of the program and deleted it, you would be able
to reinstall EZ 1...but I don't know.
This is ONE BIG reason why you should be able to KEEP your old installation
when installing a new version. If the new version doesn't "work properly"
you have a way of continuing to work while the problem is sorted out.
This is one BIG thing I applaud Cakewalk for...having the foresight to allow this...
