I have an ATL/WTL project developed using Visual Studio 2008 and up until now I have been statically linking with the CRT libraries, avoiding the need to ship them. However, I now need to consider using the dynamic libraries (DLL) instead - in order to reduce the size of the code and because I want to use the excellent crashrpt tool (which requires you dynamically link to the CRT.)

Now, MS supply both a stand-alone installer (vcredist_x86.exe) and an MSM package but this is no good for me for two reasons:

  • I am not using an MSI based installer (I am using InnoSetup).
  • My application installs on a limited user account and the vcredist_x86.exe installer will not work.

Therefore I want to ship the CRT DLLs and install then in my applications program folder. Now, this is something you can do as I found the following blog post by Martyn Lovell, the MSVC Libraries Development Lead that says:

However, if you want to install-applocal, you should make sure that your application has a manifest, and then copy the whole of this folder into your EXE directory:

X:\Program Files\Microsoft Visual Studio 8\VC\redist\x86\Microsoft.VC80.CRT

and other folders if you use more than the CRT. Make sure you include the manifest.

Just want I am after - except I don't understand this part:

make sure that your application has a manifest

My question is - how do I create an application manifest that references the CRT DLLs I want to use? The only manifest information my projects currently use is the following (which ensures the app uses v6 of the Common Controls):

/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'\"

Can someone provide me with instructions on how to work the manifest magic using Visual Studio 2008? There is a Microsoft.VC90.CRT.manifest file in my Visual Studio VC\redist\x86\Microsoft.VC90.CRT folder - do I need to use this somehow?

Note: This is a similar - but different - question to this one.

Visual Studio will generate the correct manifest for you when you pass the /MD flag.

So other than changing my 'Runtime Library' setting on the 'C/C++ -> Code Generation' page, I don't need to do anything else (other than ship the CRT DLLs of course!)?
Rob
Correct, AFAIK. (As long as you're not trying to deploy a debug version with `/MDd`)
Alex
Thanks, I'll give it a go.

Look in the build directory of your project, you'll see the manifest file.
