Right mouse click stops responding in Visual Studio 2010 for K2 Designer extension

In Visual Studio 2010 the mouse right-click may stop responding (no context menu is displayed) and the K2 toolbar disappear.

Solution

To fix the problem, perform the following steps:

1. Ensure Visual Studio 2010 is not running. Check for and shut-down the devenv.exe process if necessary.
2. Using Windows Explorer, browse to the folder with the originally extracted installation media e.g.:
   [your extraction folder]\Setup\Installation
3. Right-click on the K2 for Visual Studio 2010.msi file and select Repair

The K2 Designer extension will be repaired in a few seconds and the mouse right-click context menu and K2 toolbar will be available in Visual Studio 2010 once more.

On some systems, installing the Visual Studio 2010 SP1 will correct the issue.
