Visual Studio crashes on 'add reference'
<p>Visual Studio crashes when opening any solution and right-clicking 'references' and choosing 'add reference'. The dialog opens for a few seconds, VS crashes and restarts. Tried uninstalling and reinstalling VS2013, then uninstalling again with VS Uninstaller and reinstalling, and installing VS2015. Problem persists on both new installations. Had Beckhoff TwinCAT 3.1 installed but uninstalled also this before first reinstalling Visual Studio, to no avail.</p>

<p>Is there a registry key or specific locations where all VS installations look for packages?</p>
