In my case, VS 2013 Professional was hanging on startup because the license was no longer valid.

Last item in the log file:

<entry>
    <record>367</record>

    <type>Information</type>

And on the msdn.microsoft.com subscription page: "Your subscription is no longer active, contact your administrator."

I had to get an updated subscription from my employer.

Answer 4

Have you tried resetting user settings? It did help me:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe /ResetUserData

Answer 5

devenv.exe /ResetSettings

or

devenv.exe /ResetSetting

Worked fine for me

Answer 6

I had the same issue with Community 2015 version. I solved it with Vidas Vasiliauskas suggestion, which was to erase user settings.

The thing is that I previously had enterprise 2015 version, in which I was logged in with my Microsoft account. When trying to open community version, it tried to do so with that same account, which I believe was the cause of the issue.

Therefore, I would suggest to those with the same problem to run the following command at Command Line Prompt:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe /ResetUserData
