I reinstall all microsoft visual and don't work,it's same error,what i need to do?

(P-SERVERS)

Click on Start-> All Programs -> Accessories -> Right click on Command Prompt (CMD) -> Run as Administrator and click allow.
After that a black window should come up, and in there you type this:

bcdedit /set IncreaseUserVA 2800

Press enter and restart the computer. The problem should now be solved.
