3 Halos, 2 computers???

[Goalie]

So after I had cleaned my room for the first time in about 10 years, I found an old copy of Halo that I had bought for one of the computers.  I couldn't find this box, so I had to buy a new one.  So now I have 3 Halo disks and 2 computers that have Halo installed.

My problem is this:  All the boxes have been opened (and I believe I have all 3 disks still), so at first glance I have no way to tell which disk is installed on which computer.  Is there a way to find out which computer has which disk without uninstalling and reinstalling?

It doesn't matter which disk you use: they're all IDENTICAL.

...Now if you're asking how to tell which CD KEY was used on which when you installed them, simply get and use the Halo CD Key Recovery Tool on each system to find which CD key was used where, and make note of that along with your three CD keys in a file somewhere.

Hint: Since I've used Virtual CD/DVD drives for ages, I've squirreled away text files containing the key for any/every game I've virtualized/installed as well, so I always have them all, even on my backups of my computers....

yeah, that's what i meant, which cd key.

So did you get the Recovery Tool and get it all sorted out?

Well I got one cd key, just need to get the other one now.
