I have a program which run fine on my computer and on some client computer.
However, recently, it started to crash at launch time with a mysterious
error as in the title.

After a bit of investigation it is probably a missing native DLL dependency
in a Managed C++ library.
Investigating a bit more with depends I think the culprit is the following:

C:\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.163_x-ww_681e29fb\msvcm80.dll

On my computer I have 2 versions of it:

C:\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.163_x-ww_681e29fb\msvcm80.dll
C:\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.42_x-ww_0de06acd\msvcm80.dll

But on the target computer I have only one version:
C:\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.42_x-ww_0de06acd\msvcm80.dll

And "depends.exe" tells me that my ManagedC++ library is using the other
version:
C:\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.163_x-ww_681e29fb\msvcm80.dll

Although both version are quite old (06/2006 & 09/2006)  (i.e. it's probably
not a recent windows update) I think this is the problem.
Now why is the linker is linking to the newer version?
How can I link to the older version?
Any tips?
