Package Manager Console error

when I run the visual studio,The error message is as follows
“The PowerShell 2.0 runtime required by the Package Manager Console is not detected on this computer. Please install PowerShell 2.0 from and restart Visual Studio.”
However, when I installed powershell, the installation failed. The error message is “Unable to start the service. The reason may be that the device has been disabled or the device associated with it is not started.” The error code is 0X80070422. Who knows what is going on? How can I Install powershell correctly, my computer is windows7 Ultimate.

Thanks a lot.

The Grid Solutions Framework does not directly depend on PowerShell. Some of the included libraries reference NuGet packages however, perhaps this is what you are seeing?

Are you trying to just build the library to run one of the included tools?
