A slight problem with Microsoft's Games For Windows Live initiative is manifesting itself in the PC version of Epic Games' Gears of War, which infests stores today.

According to Microsoft, players are automatically prompted to download a Games For Windows Live update when they begin the game. However, the update refuses to install correctly, which can cause some problems.

The solution is an extremely easy one. After downloading the update and arriving at the main menu screen, simply quit of the game and restart it, which should cause the update to install. Alternatively, players may download and apply the update separately.

"The good news is that once you go through the above process, you won't have to do it again," reads a post on the Microsoft-sponsored Gamerscore Blog. "Microsoft Game Studios is working on a title update to be released in the near future that will allow users to avoid manually exiting "Gears of War" to apply the update."

"Happy curb-stomping," the entry concludes. For more on Gears of War, check out Nick Breckon's in-depth review.
