How to determine if the 32-bit Visual Studio 2013 redistributable is installed on a user's machine reliably via the Registry?

Question

I am using DeployMaster to build an installer for a 32-bit Windows application written in C++ using Qt.

The executable depends on the Visual Studio 2013 redistributa

Answer 1

The key you need is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\DevDiv\vc\Servicing\12.0\RuntimeMinimum.

Answer 2

Just in case someone is looking at this, but is using NSIS to deploy their program.

You check:

ReadRegDword $0 HKLM "SOFTWARE\Wow6432Node\Microsoft\DevDiv\vc\Servicing\12.0\RuntimeMinimum" "Install"

If $0 equals 1, then it is installed. If not, it isn't.

Answer 3

I found it here:

32bit
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{13A4EE12-23EA-3371-91EE-EFB36DDFFF3E}
or
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{13A4EE12-23EA-3371-91EE-EFB36DDFFF3E}

64bit
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{A749D8E6-B613-3BE3-8F5F-045C84EBA29B}

This is probably better than the devdiv keys, as its the Windows key used to uninstall the msi, if its been installed. Now I just wish Microsoft's devdiv could talk to the Windows team so we can have a canonical place to detect this stuff, and a canonical name for Redistributable. Hint Microsoft, it ain't called 'minimum runtime'

Answer 4

I'm using these reg keys: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\12.0\VC\Runtimes\x86 Installed HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\12.0\VC\Runtimes\x64 Installed

I've confirmed that they appear only after the redist is installed, and they more closely match the ones for previous versions. e.g. VC++ 2010 is: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\VC\VCRedist\x86 Installed HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\VC\VCRedist\x64 Installed
