As far as I can tell, we can not install both versions on our computer. It seems version 7 always overwrites version 6. I think it would be nice if we could install both versions and let version 6 continue to maintain version 6 programs and use version 7 for new programs. That way we don’t have the headaches of upgrading our version 6 programs.
Maybe I’ve missed the boat, but its seems that version 7 doesn’t particularly like version 6 programs.
