After the purchase, create a .REG file backup using the "Backup RegKey" option of the Addon Manager, that will be named "fsdreamteam_ohare.REG" in you FS9 root folder, and move this file to the other PC, then install OHare Trial on the other computer.
- Launch FS, go in Windowed Mode (not always necessary, but it's better), it will ask if you want to activate. Reply "Yes", the screen will go black and, after a while (give it some time, it might be up to a minute), it will automatically detect there's no internet connection, so a dialog will appear with some options:
- Select "Activate Using a Different Computer that has Web access" - It will present you with a serial number called "Installation ID". Save this code to a thumb drive, and go to any PC with web access.
- Go to
http://activate.esellerate.net and type this ID into the field. It should reply back with another long code. Save this code and return to the non-internet connected PC.
- Launch FS and wait again for the manual activation screen to come up. Now select "I already have an Activation Key and would like to Activate Now". Type the code you obtained from the web from the other PC, and it should activate.
