Detect if Visual C++ Redistributable for Visual Studio 2012 is installed

How to detect if Visual C++ Redistributable for Visual Studio 2012 is installed?

I tried Google it and nobody has asked this question, surprise!

It depends on what version you are using. These two 2012 keys have worked well for me with their corresponding versions to download for Update 4. Please be aware that some of these reg locations may be OS-dependent. I collected this info from a Windows 10 x64 box. I'm just going to go ahead and dump all of these redist versions and the reg keys I search for to detect installation.:

version caveat: Per user Wai Ha Lee's findings, "...the binaries that come with VC++ 2012 update 4 (11.0.61030.0) have version 11.0.60610.1 for the ATL and MFC binaries, and 11.0.51106.1 for everything else, e.g. msvcp110.dll and msvcr110.dll..."

Additional Caveat -- 2012 Update 4: Per user Krptodr VC++ 2012 Update 4 (x86) shows under GUID {95716cce-fc71-413f-8ad5-56c2892d4b3a}

^^ The GUID's provided are for the installer package. However, these branch off into two other GUID's respective of their arch type. For further information please see the following source How to check if the Microsoft Visual C++ Runtime is installed

Visual C++ 2017

_{^{Consider using the 2015-2019 bundle as an alternative}}

Caveat: There's either a new 2017 registry convention being used, or it hasn't been finalized, yet. As I'm guessing the upper-most keys of: [HKEY_CLASSES_ROOT\Installer\Dependencies\,,amd64,14.0,bundle] and [HKEY_CLASSES_ROOT\Installer\Dependencies\,,x86,14.0,bundle]

are subject to change, or at least have different nested GUIDs, I'm going to use list the key that ends with a GUID.

Visual C++ 2019 (2015-2019 bundle)

Caveat: There's another new registry convention being used for Visual C++ 2019. There also doesn't appear to be a standalone installer for Visual C++ 2019, only this bundle installer that is Visual C++ 2015 through 2019.

Try

HKLM\SOFTWARE\Microsoft\DevDiv\VC\Servicing\11.0

as a starting point. I will be using this as a check for installing the VC++ 11 (VS 2012) runtime.

You can check for the Installed value to be 1 in this registry location: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\11.0\VC\Runtimes\x86 on 64-bit systems. In code that would result in accessing registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\11.0\VC\Runtimes\x86. Notice the absence of Wow6432Node.

On a 32-bit system the registry is the same without Wow6432Node: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\11.0\VC\Runtimes\x86

There is no installcheck element in the bootstrapper package manifest shipped with Visual C++. Guess Microsoft wants to always install if you set it as a prerequisite.

Of course you can still call MsiQueryProductState to check if the VC redist package is installed via MSI, The package code can be found by running

wmic product get

at command line, or if you are already at wmic:root\cli, run

product where "Caption like '%C++ 2012%'"

The answer to this simple questions is unfortunately not a simple one, but working in 100% of all systems, and even extendable to the numerous .net frameworks.

The complexity comes from the fact that there are (and were) many VC runtimes revisions which could lead to the case that although VC10 runtimes were installed, their build number was not recent enough so your EXE wouldn't start unless you either installed the very exact runtimes you required or one of the newer runtimes which enable this and previous versions for the same major version to run with it (the side-by-side hell). Also, if you have a 64 bit EXE, you will have to check for both, the 32 AND 64 bit runtimes.

That said, the only reliable way to determine whether the runtimes for your EXE are installed is to attempt to run the EXE - or a another EXE which is built with the same settings as your main EXE and whose only purpose is to do - nothing. Just run (which means the runtimes are installed) or fail to run (when not installed).

I did the following for an installer which required the VC10 32 and 64 bit runtimes installed: The installer attempts to launch all dummy EXEs and if it succeeds, the corresponding runtime is considered to be installed. This also resolves the 32/64 bit scenario.

This, by the way, works also to determine if the proper .net framework is installed, which is very tricky in Windows 8 and 10, as the downloadable built-in .net 3.5 support also supports the .net versions 3.0 and 2.0 - there are no registry entries for these. (And worse, you cannot even use the standard framework installers here, you must use the built-in support and download it via Windows, or rebuild your app with .net 4, but that's another story).

The C++ dummy EXE can be built using a project with the following code (and another one in a 64 bit configuration if necessary):

int _tmain(int argc, _TCHAR* argv[])
{
    return 0;
}

Remember to set the project's properties Use of MFC to Use MFC in a shared DLL. The executables will be around 4KB in size - a small price to pay for a sure result.

To give your users a nice installation experience, you could do the following (sample code is for NSIS):

Function TryLaunchApplication
  Pop $1 ; pathname
  nsExec::Exec $1
  Pop $0

  ${If} $0 == "error"
  ${OrIf} $0 != 0
    Push 0
  ${Else}
    Push 1
  ${EndIf}
FunctionEnd

and call it in a function, e.g. CheckRuntimes

Function CheckRuntimes
  ; Try to execute VC++ 10 application (32 bit)
  Push "Vc10RuntimeCheckerApp.exe"
  Call TryLaunchApplication
  Pop $Vc10RuntimesFound

  ; Add 64 bit check if required.
  ; Remember to try running the 64 bit EXE only on a 64 bit OS,
  ; which requires further checks.

  ; Try to execute .net application
  Push "DotNetRuntimeCheckerApp.exe"
  Call TryLaunchApplication
  Pop $DotNetFrameworkFound
FunctionEnd

Then launch the runtime check e.g. when leaving the Welcome page and cache the result, so you don't have to re-check every time the user clicks on the "Back" and "Next" button.

Next, make a read-only section in the install tree and pre-select or unselect it on the a function which is executed before the Components page is shown.

This will make sure that the installation of each missing runtime component is mandatory, and is skipped if it is already present.
