Nuget 1.6 install issue

Dec 16, 2011 at 8:00 PM


In admin mode I uninstalled Nuget 1.5 from vs, restarted vs  in admin mode, installed 1.6, and then restarted vs. Nuget worked for several days.

Today, the package manager wont come up - it doesnt give me an error, it just wont load. If I try to uninstall it, the uninstall button is greyed out (which I assume means that the addin is in use). If I restart vs, then I can uninstall.

I have tried uninstalling Nuget and reinstalling it several times (no error messages generated)

Any ideas?
 

Thanks!

I have gone through the whole registry and removed all 'nuget' keys/values.

Then it installed and worked.

I tried this, but it didnt work, and now I cannot uninstall - I get the error "Cannot create a file when that file already exists"

 

Any ideas?

I erased the deleteme files as directed in the FAQ, and the "Cannot create" message is gone, but I'm back to not being able to open the package manager console

Help!

Found that the signature mismatch problem is a known issue, and needs a fresh install to be avoided. Uninstall old version, install new version. Ref.: http://docs.nuget.org/docs/release-notes/nuget-1.6
