I have been facing lots of problems while playing games on my PC. Mostly when I have Windows 7 on it. The most problem was the graphics+compatibility, and though I managed the graphics and compatibility the games would still not run. I play mostly RoadRash, Counter Strike copied from my friend. I play most of the games without install (i.e. I copy the games from my friends and Run). When I had Windows XP, I didn’t faced any type of problem regarding this. But since I had Windows 7, I have been facing this problem. Everything was fine, I did the same as what I used to do in Windows XP, yet the game couldn’t run. The I thought of registry. Registry need Higher level access to be changed. And as of the security in Vista and Windows 7, the access is limited as equal to guest until it is opened in Administrator mode. So I thought of opening the game file in Administrator mode as well as registered the game in administrator mode. And the problem was solved. Like for some game, for the registration there are some executable files which writes in the registry and keep all the configuration in it. But when the game loads, the game says “Re-install”. So open the Registering file in administrator mode so that it will install the game in your system. I have a screen shot for this.
And hence the main problem is the user level access. Play the game.Have fun
