Visual Studio 2015 does not start

Question

We have installed Visual Studio 2015 Professional on Windows 7. It was working fine. But after we installed updates from the menu Tools-->'Extensions and Updates' today the Visual studio does not start anymore. we tried using 'run as administrator' as well. From the Start menu we right click on 'Visual Studio 2015', then 'run as administrator', the usual dialog box asking for permissions appears, we click on 'Yes', splash screen for Visual Studio appears for a second and then disappears. On the Task Manager, it does not appear as well.

Re-starting the system does not help either. .NET 4.6 is installed and Visual Studio 2012 on the same system is working fine.

UPDATE 1 The issue started after we installed the last update (from within VS2015) that had something to do with universal apps I think.

UPDATE 2 At the exact time when I start VS2015, one Windows Event log gets generated under security section as follows:

EventID 6281
Microsoft-Windows-Security-Auditing
Audit Failure
Message: Code Integrity determined that the page hashes of an image file are not valid.
The file could be improperly signed without page hashes or corrupt due to unauthorized modification.
The invalid hashes could indicate a potential disk device error.

Answer 1

Nothing of above helped me, What helped me was to copy devenu.exe from other computer which had VS installed and then replacing it with mine computers devenu.exe.

Answer 2

For me it only shows Visual studio 2015 window without disappearing and showing IDE or any error.

Non of following solutions worked for my normal domain user but there was no issue running it with administrator.

• Devenv.exe /ResetSettings
• Reinstalling
• Repairing
• Watching event viewer for more details
• Cleaning temp and cleanup and finally seeing some error

Finally I deleted my whole profile from admin via [System properties]-> [Advanced] -> [Profile] and it resolved the problem.

Just before that copy your user folder somewhere or at least your desktop and user folders and also your bookmarks and settings.

Answer 3

I tried several methods above and even re-installed VS but it did not work. The final solution was to really completely remove all the settings and registries of VS with the tool VisualStudioUninstaller. After uninstalling and re-installing it, it is up again.
