I don't think I would worry about V6 programs becoming unusable. While V7 does have many new functions and features, it's not like the big V5 to V6 change. > Are most users able to have both installations working on the same > machine?

Both of them work properly, and V7 sucked up my init.m etc. from V6. On a spare XP machine in my office (an old hand-me-down that I have around for students to use when they come in for office hours etc.), there were problems getting V6 and V7 both to work. Apparently both were trying to use the same mathpass file, and since the passwords are different, there was a conflict. After registering V7, V6 would ask for license information; if you put it in, that would wipe out the V7 password. In my Vista installations, there are two different mathpass files, in different directories, and all is well. I don't know if the problem on my spare machine is an XP issue, or if it's because there are multiple user profiles on this machine (with log-in authentication over the university network), whereas the two Vista machines are set up for a single user. It might be possible to resolve the mathpass conflict by installing V7 to a different directory than the default, but rather than muck around with it this late in the semester, and given that the students are still using V6, I ended up uninstalling V7 on my spare machine for now, and will get rid of V6 and re-install V7 during the semester break. -- HPR http://homepages.together.net/~hpr/daveorama/
