VSTS install error

During the installation of VSTS RTM, I am getting the below error. Does anyone know how to pass this problem?

The exception unknown software exception (0xe053534f) occurred in the application at location 0x77e55dea.


UPDATE: The problem is msvb7.dll. I need the new version of this dll. More information is on
