Signature issue with NuGet Package Manager

I am trying to install NuGet on a Windows 7 machine running Visual Studio 2010 Professional. I have never used NuGet before. It is throwing this error:

5/28/2013 9:28:41 AM - 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. at VSIXInstaller.Common.VerifyMatchingExtensionSignatures(IInstalledExtension installedExtension, IInstallableExtension updateExtension) at VSIXInstaller.InstallProgressPage.BeginInstallVSIX(SupportedVSSKU targetAppID) 5/28/2013 9:28:41 AM - Install 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. at VSIXInstaller.Common.VerifyMatchingExtensionSignatures(IInstalledExtension installedExtension, IInstallableExtension updateExtension) at VSIXInstaller.InstallProgressPage.BeginInstallVSIX(SupportedVSSKU targetAppID)

Does this error mean that NuGet is already installed on my machine? (Maybe for a prior user?) What steps can I take to debug this problem? I'm not really sure where to go from here.

I could not find this problem on the known issues page.

Simply uninstall NuGet first and make a clean install.

Sometime in the past, the signature has been changed causing this problem.

BTW: The very first problem on the known issues page refers to your exact problem.
