now i got this game running but if i want to do the same with my other game like hawx or assassins creed how can i get 4 things version , name , language, path ? when all of my games could be found in c>program files>etc.
or is there any software that will extract the reg file for me ?
thank you .

 

I don't think this is going to be possible in every case, because you would need to be intimately familiar with the workings of every game to be able to get all the necessary registry entries.

Personally, I would pretty much only trust the installers of a game to create the registry keys needed to support that game.

If formatting/reinstalling is such an issue for you, maybe you would be best to consider an system imaging program to save/backup the entire contents of your hard drive. This would preserve the Operating System, all program installations, and your data.

Majorgeeks has a number of good options in the Backups section of the downloads page. I can personally recommend Acronis True Image

 

thank you , i'll try that .

 

Run a packager like cameyo or a program like regshot. It will take a snapshot of the reg before and then after the install and show you the difference.
And remember if you like games, buy them!!
