I'm compiling a project which uses multiple DLL and compiles with VS2008. After a recent windows update DLLs compiled on my computer stopped working on other computers.

After some investigation it turned out that it updated the CRT redistributable library which I'm compiling with from version "9.0.21022.8" to version "9.0.30729.4148"

This is evident from the Manifest file of the EXE i'm compiling. it contains the following:

  <dependency>
    <dependentAssembly>
      <assemblyIdentity type="win32" name="Microsoft.VC90.CRT" version="9.0.21022.8" processorArchitecture="amd64" publicKeyToken="1fc8b3b9a1e18e3b"></assemblyIdentity>
    </dependentAssembly>
  </dependency>
  <dependency>
    <dependentAssembly>
      <assemblyIdentity type="win32" name="Microsoft.VC90.CRT" version="9.0.30729.4148" processorArchitecture="amd64" publicKeyToken="1fc8b3b9a1e18e3b"></assemblyIdentity>
    </dependentAssembly>
  </dependency>

Meaning it wants to use two different versions of the CRT at the same time. the second version is needed by the code which I'm compiling right now and the first version is needed by older dlls which were compiled a few weeks ago.

In the computers where the application is deployed this becomes a problem since they get their CRT dll from a local folder called Microsoft.VC90.CRT and not from WinSXS. This folder can't contain two different versions of the dll.

Is there a known solution to this issue or do I need to start compiling all of the other DLLs with the new CRT?
