How to repair Resharper?

I have problem with Resharper - all it's menu options are greyed, no shortcuts working...

I've tried run installer with repair option - no success

Also tried uninst开发者_JAVA百科all / install back - same.. :(

ReSharperSetup.4.5.1288.2.msi

Can someone advice how to make it working back?

I had a similar problem with VS2010 and version 5.1.1753.4 of ReSharper. ReSharper is shown as "Not Loaded" in VS2010 About box and no ReSharper menu is visible. After multiple install/uninstall/register MSXML6/attempts of ReSharper, I finally figured out that:

A REINSTALL DOESN'T AUTOMATICALLY RE-ENABLE RESHARPER IF IT WAS DISABLED AT THE TIME OF DEINSTALLATION!

So the simple fix is just got to Tools.Options.ReSharper.General in VS2010 and enable it again.

In case ReSharper is listed as [Not Loaded] under Help > About Visual Studio, this most likely means that msxml6 component registration is broken. To fix this problem, just re-install MS XML Core services 6.

Tools -> Import and Export Settings -> Reset all settings

Source.

See if it's even loaded by ticking the checkbox it in the Tools → Add-in Manager.
