VS 2012 Update 3 broke my VS

Question

I am using Windows 8 64 bit machine with VS 2012 ultimate. After installing Update 3 and restarting the machine, I get following error whenever I try to open VS.

---------------------------
devenv.exe - System Error
---------------------------
The program can't start because MSVCR110.dll is missing from your computer. Try reinstalling the program to fix this problem. 
---------------------------
OK   
---------------------------

The said file is already present in C:\Windows\System32 folder. Please let me know what can be done here..don't want to reinstall that monster again.

You are looking in the wrong directory, it is c:\windows\syswow64 since VS is a 32-bit program. It probably isn't the only DLL that's missing, also check for msvcr110d.dll and msvcp110.dll for example. Using the redist is not a fix, you won't get the debugging versions of those DLLs. Your machine is pretty sick when DLLs go missing like that. You'll need a doctor, not a programmer. — Hans Passant, Jul 06 '13 at 11:48
Fwiw, forgetting that the installer wanted you to reboot but you canceled that would be a happier explanation. Reboot before you get drastic. — Hans Passant, Jul 06 '13 at 11:55

You need to check where your projects are being loaded. I have VS installs under both x86 and 64. You'll need downloads for both on a 64 bit operating system.

http://www.microsoft.com/en-us/download/details.aspx?id=14632 http://www.microsoft.com/en-us/download/details.aspx?id=30679

Please see:

Some basic tips:

Ensure you have run the install with Administrator rights.

VS won't always ask for a computer restart. However, reboot your computer.

A note about this update.

Note Visual Studio and Team Foundation Server (TFS) installation mechanics are different. The Visual Studio update installs on top of whatever is already installed on the computer. The TFS update is a full layout that replaces whatever is installed on the computer. Before you try to apply the TFS update, make sure that you have a full backup of your current databases. If the TFS update installation fails, you will be unable to restart the update or roll back to the earlier version of TFS without performing a restore procedure.

Installing both updates solved my problem. However, now when i open VS 2012, it still prompts me to install VS 2012 Update 3. — NoobDeveloper, Jul 06 '13 at 11:50
That is a new problem and fixed by running the update 3 again and doing a repair this time. Thanks a lot. — NoobDeveloper, Jul 06 '13 at 12:16

If you get this error it means you don't have Microsoft Visual C++ Redistributable 2012 Update 3.Try to download it from http://www.microsoft.com/en-us/download/details.aspx?id=30679 .Hope this helps.

Since it is a 64bit system, copying the missing file to the C:\Windows\SysWOW64 folder should solve your problem. If it keeps failing for other dll just keep copying.

Copy the file from C:\Windows\System32 to C:\Windows\SysWOW64 ? My C:\Windows\SysWOW64 has msvcr110_clr0400.dll but not msvcr110.dll – NoobDeveloper Jul 06 '13 at 11:18
Yes exactly. The SysWOW64 folder can contain 32bit dlls that will be run in the context of a 64bit application – Moslem Ben Dhaou Jul 06 '13 at 11:20

With same error (MSVCR110.dll not found) really reinstalled Microsoft Visual C++ Redistributable 2012 not solved all problems. Some VS tools report - not found msvcr110_clr0400.dll. After repair installation of .net 4.0 (or 4.5/4.5.1) all work fine.
