[ACCEPTED]-How to detect VC++ 2008 redistributable?-redistributable

I don't think any of those solution can 14 help when your using different OS ! For 13 ex, MsiQueryProductState will always returned 12 -1 using Vista VC8.0

while -1 for VC8.0/8.0 11 SP1/9.0 with Windows 7 ! So the GUID solution 10 that microsoft provided, doesn't work in 9 all cases

so i guess i'm forced to stuck 8 with the %windir%\winsxs approach and search 7 for

• x86_Microsoft.VC80.CRT*
• x86_Microsoft.VC90.CRT*

For those who are looking for all GUIDs, Here 6 is a list i created:

Quick and dirty:

if (LoadLibrary(L"msvcrt80.dll")!=NULL)
{
  // it is installed
}

Loadlibrary will handle 1 searching the paths for you.

looks like there is another solution proposed by a Microsoft-Developer, using 12 MsiQueryProductState API, alas also relying on the GUIDs.

Update: The code 11 went live yesterday and seems to be working 10 fine. Here is what is beeing done: It is 9 checked for the latest-known-to-me GUID 8 AND the path² to-where-it-is-supposed-to-be-installed. If 7 both fails, it is installed. This seems 6 to work fine.

Additionally, it is installed 5 with the command line arguments "/qb" which 4 means "unattended but not invisible". See 3 this other blog post about those params.

FWIW, GUIDs for Microsoft 2 Visual C++ 2008 / VC90 SP1 Redistributable 1 - x86 9.0.30729

• 64bit 30729.17: 8220EEFE-38CD-377E-8595-13398D740ACE
• 32bit 30729.17: 9A25302D-30C0-39D9-BD6F-21E6EC160475
• 32bit 30729.01: 6AFCA4E1-9B78-3640-8F72-A7BF33448200

² The path: $WINDIR\WinSxS\x86_Microsoft.VC90.CRT_1fc8b3b9a1e18e3b_9.0.30729*

Check for $WINDIR\WinSxS\x86_Microsoft.VC90.CRT_* if, for example, you're checking 1 for the Visual Studio 2008 redistributable.

I open-sourced a Visual C++ project on Github that checks for VC++ redistributable DLLs specifically and made it 7 available under the Apache 2.0 license.

It 6 has three different methods for checking 5 for the availability of VC++9 and VC++10 4 runtimes:

1. Checks the MsiQueryProductState APIs;
2. Inspect the contents of the WinSxS folder for matching product directories; and
3. Checks the current working directory for any local versions of the VC++9 and VC++10 runtimes (and inspects their contents.)

edit: Here's a sample of what using 3 it actually looks like:

 wcout << _T("Checking for the availability of VC++ runtimes..") << endl;
 wcout << _T("----------- Visual C++ 2008 (VC++9) -----------") << endl;
 wcout << _T("Visual C++ 2008 (x86) ? ") << (IsVC2008Installed_x86() ? _T("true") : _T("false")) << endl;
 wcout << _T("Visual C++ 2008 (x64) ? ") << (IsVC2008Installed_x64() ? _T("true") : _T("false")) << endl;
 wcout << _T("Visual C++ 2008 SP1 (x86) ? ") << (IsVC2008SP1Installed_x86() ? _T("true") : _T("false")) << endl;
 wcout << _T("Visual C++ 2008 SP1 (x64) ? ") << (IsVC2008SP1Installed_x64() ? _T("true") : _T("false")) << endl;

I licensed the crt-detector project 2 under Apache 2.0, so feel free to use it 1 in your own applications.

Update for anyone else hitting this problem:

1) If 16 you have Visual Studio installed, the required 15 DLLs will be present, but the "redist package" is 14 not, so the registry keys are missing. (i.e. this 13 will give a false negative). However, installing 12 the redist over the top in this situation 11 is harmless.

2) Every major release of the 10 redist (Any combination of VS2005/VS2008, x86/x64/IA64, and 9 service packs: SP1,ATL security update) has 8 a different GUID. Take care if you are expecting 7 to deploy your application on both x86 and 6 x64 PCs.

3) If you use LoadLibrary or a check 5 for Dll files, make sure you target the 4 correct version. If you look for "any" copy 3 of msvcrt80.dll (etc) then you won't be 2 able to tell if it is the version your program 1 was linked to.

Product code for "Microsoft Visual C++ 2008 2 Service Pack 1 Redistributable Package MFC 1 Security Update (x86)" is {9BE518E6-ECC6-35A9-88E4-87755C07200F}

You can check for the files under the WINDOWS\WinSxS 4 directory to see which versions you have 3 installed. Often many versions can be installed 2 at one time so you might need to check the 1 specific versions you have installed.

Found registry entry for VC2008 redistributable. Here 1 is my solution:

BOOL IsVC2008RedistInstalled(LPCTSTR pLogFile)
{
    TCHAR szLogEntry[256];
    memset(szLogEntry, '0', sizeof(szLogEntry));
    HKEY hKey;
    LONG lErr;

    TCHAR csid[256];
    _stprintf( csid, _T("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\{9A25302D-30C0-39D9-BD6F-21E6EC160475}"));
    lErr = RegOpenKeyEx(HKEY_LOCAL_MACHINE, csid, 0, KEY_QUERY_VALUE, &hKey);
    if (lErr == ERROR_SUCCESS)
    {
    _stprintf(szLogEntry, _T("VC2008 Redistributable was installed before.\n"));
    toFile(pLogFile, szLogEntry);
    return TRUE;
    }
    else
    {
    _stprintf(szLogEntry, _T("VC2008 Redistributable was not installed before. %ld\n"), lErr);
    toFile(pLogFile, szLogEntry);
    return FALSE;
    }
}

I'd like to extend the GUID list with the 12 following values:

32bit 30729.17
{9A25302D-30C0-39D9-BD6F-21E6EC160475}
32bit 11 30729.01
{6AFCA4E1-9B78-3640-8F72-A7BF33448200}
64bit 10 30729.17
{8220EEFE-38CD-377E-8595-13398D740ACE}
64bit 9 30729.01
{0DF3AE91-E533-3960-8516-B23737F8B7A2}
VC++2008 8 (sp1)
{3C3D696B-0DB7-3C6D-A356-3DB8CE541918}
VC++2008 7 (original)
{FF66E9F6-83E7-3A3E-AF14-8DE9A809A6A4}
IA64 6 30729.01
{22E23C71-C27A-3F30-8849-BB6129E50679}
32bit 5 30729.4148
{7B33F480-496D-334A-BAC2-205DEC0CBC2D}
Visual 4 Studio 2008 Professional SP1
{D7DAD1E4-45F4-3B2B-899A-EA728167EC4F}
32bit 3 30729.01
{F333A33D-125C-32A2-8DCE-5C5D14231E27}

So 2 please decide, whether it's a good idea 1 to check the presence of VCredist by GUIDs.

The surest way is using the MsiQueryProductState API with the 2 GUID of the different vcredist versions.

It 1 works!

Regards.
