I don't know where jenny is, as she usually has the correct way to do these things.
On my Win98, and the cd in the drive, I just went to My Computer, clicked on that and then clicked on the disk that is showing in the CD/Rom drive, then double clicked on the file called t7g.exe, and then followed the directions. You will have to use your direction keys to select the things in the boxes, but usually you can accept the recommended ones by just clicking yes. When the install is complete, you then go to DOS and type T7G to run. You have to go to DOS every time you want to play the game. To get out of the game, after you do an exit, then it sends you back to DOS, and you have to type EXIT to get back to Windows.
Hope this helps.
Otherwise Jenny can tell you how to use the Run feature and what to type in. I never bother with that.
