Microsoft SQL Server Installation Issue Fix

I was installing Microsoft SQL Server 2012 on a development server and kept getting an annoying error message:

Microsoft SQL Server 2012 Install Error Message

The following error has occurred:

An error occurred during the installation of assembly ‘Microsoft.VC80.MFC,version=”8.0.50727.4053″,publicKeyToken=”1fc8b3b9a1e18e3b”,processorArchitecture=”x86″,type=”win32″‘. Please refer to Help and Support for more information. HRESULT: 0x800736CC.

KB Article 2688946 describes a very similar issue. I eventually found a fix in the form of Cumulative Update 2 (KB2703275) Here is what you need to do to fix it:

  1. Completely close the SQL 2012 installer (it might just crash and close itself).
  2. Use Control Panel to uninstall Microsoft Visual C++ 2010 x64 Redistributable and Microsoft Visual C++ 2010 x86 Redistributable.
  3. Download Cumulative Update 2 from (449398_intl_x64_zip.exe)
  4. Create C:\Updates
  5. Extract 449398_intl_x64_zip.exe to C:\Updates to get SQLServer2012-KB2703275-x64.exe
  6. Run the Installer again from the command line with the following (all on one line):
    setup.exe /Action=Install /UpdateEnabled=True /UpdateSource="C:\Updates"
  7. Install as usual and the issue goes away.

Let me know if this worked for you by leaving a comment. I’m curious to know how widespread this issue is.
