问题
We were running VS2012 Pro Update 1 and just installed Update 4 (VS2012.4.exe) yesterday. The installation appeared to be successful - no error messages, etc., and the control panel definitely shows that Update 4 (11.0.61030) was installed.
However, when we start VS it still says that we're running Update 1 (11.0.51106.01).
We re-ran vs2012.4.exe with the "Repair" option and re-booted the server, but nothing changes.
We're running on Windows Server 2008 R2, SP1 with .Net 4.5.50948.
Is there something else we have to do?
