Answer by Learner for Detect if Visual C++ Redistributable for Visual Studio 2012 is installed

I would check the Installed value of

HKLM\SOFTWARE\[WOW6432Node]\Microsoft\Windows\CurrentVersion\Uninstall\{VCRedist_GUID} key

• where GUID of VC++ 2012 (x86) is {33d1fd90-4274-48a1-9bc1-97e33d9c2d6f}
• WOW6432Node will be present or not depending on the VC++ redist product
