Hi zhoudani. At first I was trying to find where in SIM Commander 3 game choice area (where you choose which game you want to play. This is tye window with the icons for each game that is on your PC. I could not find a wizard button there.
So I tried the X-Sim Extractor button and the wizard button is in the bottom left corner of the panel. You then have to work out where you have to enter the location of your Firefox .exe file. This is where you, and I, will have problems.
At first the simulation played from the X-Sim Extractor button page by pressing "Play the game" on the right side. However later I tried again and it did not work. I think it is where your put the .exe location into which query field that is the problem.
Don't get much time to test this at the moment. You may have to trial and error with the location.
Guess this is not much help but sirnoname helped me and I would like to help you.
