[Bricklayer]

I recently downloaded Game Booster in order improve the performance of some of my resource-thirsty games, but I encountered some problems after running it. Installation went well every time I tried to run it, a message pops up saying "gamebooster.exe is not a valid Win32 application". I am running Windows XP on my computer. Please help!

In some cases, incomplete or erroneous download of Game Booster from your default web browser i.e. Internet Explorer may cause such error message. Using another browser to download Game Booster may resolve this issue. If you still have same error then create a new user account and from there use Mozilla Firefox to download it.

If you are having this issue when you try to run the program then that means the program is still unregistered under Windows Registry and so you need to perform the steps to register it in order to run it as normally it should be.

1. Click Start and then Run
2. Under command prompt, type the following command and press Enter:
regsvr32 / i SHELL32.DLL
