    copied!<p>I have the version of NuGet that comes with MVC3 (1.0), but when I try to upgrade to the latest version (currently 1.4) it failes and I get this in the log file:</p> <blockquote> <p>6/27/2011 1:25:08 PM - VSIXInstaller.SignatureMismatchException: The installed version of 'NuGet Package Manager' is signed, but the update version has an invalid signature. Therefore, Extension Manager cannot install the update. at VSIXInstaller.Common.VerifyMatchingExtensionSignatures(IInstalledExtension installedExtension, IInstallableExtension updateExtension) at VSIXInstaller.InstallProgressPage.BeginInstallVSIX(SupportedVSSKU targetAppID)</p> <p>6/27/2011 1:25:08 PM - Install Error : VSIXInstaller.SignatureMismatchException: The installed version of 'NuGet Package Manager' is signed, but the update version has an invalid signature.

Any idea what I'm doing wrong?</p>
