If this post can save one other person the days I spend searching google its worth it - whew...

First, I could not download. It would even bring up the option to save or open. This was using IE. I tried clearing temp files and nothing helped. I finally used the Mozilla Firefox browser and downloaded without not trouble at all.

Next, when I tried installation, it would always try repairing another program I have on this computer. No matter how many times I tried it was always 'repair' or 'remove' the other program. After searching, found out if you make a directory 'gmax' in the root of your C drive and run from there, it works.

Finally, registration was easy. Whew!
