Updating NuGet Package Manager

by Ross on June 14, 2012 at 8:55 AM under Visual Studio

Unable to update NuGet Package Manager because you're seeing this error?

VSIXInstaller.SignatureMismatchException: The signature on the update version of 'NuGet Package Manager' does not match the signature on the installed version. Therefore, Extension Manager cannot install the update.

Just do the following:

  1. Run Visual Studio as administrator and uninstall the existing NuGet Package Manager through the extension manager.
  2. Close VS
  3. Go to Add/Remove Programs and make sure NuGet is uninstalled in there. Note that you can't just uninstall it from here, because VS will still think it's installed for some reason.
  4. Run the new NuGet installer.
  5. Done!
