REINSTALL VISUAL STUDIO 2010 SHELL FULL VERSION
(vs2010 was not a full version of Visual studio anyway in my case - it came with SQL Server 2014 as Management Console replacement and screwing things ever since it got installed. I went to my registry and just disabled VisualStudio.DTE.10.0 entry by renaming it to "VisualStudio.DTE.10.0 disabled" and everything magically works now.

Unity (or something inside it, I don't know, may be some COM object), when it attempts to start a handler for the Visual Studio, traces all the versions of VS from lower versions up in registry keys HKCR\.0 in order to figure out what handler to run. Reinstall is required." popupĪfter getting frustrated Nth time, and hours spent on internet in search for answers, and finally getting it traced with friendly Process Monitor it came up to this: I also tried to launch PI Processbook once Visual Studio was uninstalled and the configuration setup did not show up. Do not uninstall any of the net frameworks at this time.
REINSTALL VISUAL STUDIO 2010 SHELL LICENSE
I have Visual Studio 2013 installed, and after installing SQL Server 2014 with Tools, Unity had problems with starting VS2013 as shell for project editing with infamous "Invalid license data. I did uninstall Visual Studio Community 2013, run CCleaner both 'Cleaner' and 'Registry', reboot, reinstall Visual Studio, reboot and the problem still persist. 8) With add/remove programs, uninstall anything having Microsoft Visual Studio, Microsoft SQL Server, Microsoft 20xx Shell, Microsoft 20xx C++ runtime, Silverlight, Microsoft Web Deployment, Web Folders, Report Viewers, and anything similar.
