    I got into VS 2010 Premium this morning, and was notified of the fact that there was a new version of the NuGet installer add-in.  So I went to install it.  However, I got an error message.  Here's the error message:

    It's a known problem... you have to uninstall the NuGet package and then install the newer package for it to work.

    Simply uninstalling with "Add Remove Programs" may not clear the problem up - it didn't for me. Try the advice for "Cannot uninstall NuGet for Windows Phone Tools" in the known issues document, which basically says:

    Windows Phone Tools does not have support for the Visual Studio Extension Manager. In order to  uninstall NuGet, run the following command.

    vsixinstaller.exe /uninstall:NuPackToolsVsix.Microsoft.67e54e40-0ae3-42c5-a949-fddf5739e7a5

    This worked even though the phone version had reported as being installed successfully, and the Visual Studio had been the one with the error.

    Run VS as Administrator, and the UnInstall option is available. 

    Uninstall -> Restart -> Install new version.
