Visual Studio 2010 + ReSharper Not Working

I've installed ReSharper 5 on two installations of Visual Studio 2010 Professional. In both cases, ReSharper claims it has installed successfully - but Visual Studio doesn't recognize the extension. It doesn't show up in the Extensions Manager, doesn't appear in Help - About - Installed products, and can't be found anywhere else in the environment.

I've tried install / uninstall of both Visual Studio and ReSharper, computer restarts, etc. Both machines have Visual Studio 2008 and ReSharper 5 works fin开发者_JS百科e in these IDEs, and both machines are running Windows 7.

I've found other people online with this issue, but no solutions. Anyone know how to fix this?

Check that ReSharper is enabled in Tools->Options->ReSharper. Suspend and unsuspend it, in case that helps (I've heard that work before). Note that ReSharper will notice if more than one computer on a given network is running the same license, and disable all but one of the instances that are running. Check that hasn't happened to you.

Run devenv /resetskippkgs, solved my issues in Visual Studio 2008

I've fixed the problem by just copying the JetBrains folder from other version of Visual Studio:

This is visual studio 2010 folder for extensions: c:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\

This is visual studio 2012 folder for extensions: c:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\

I just copied from 2012 folder the 'JetBrains' and pasted to the 2010 extensions folder.
