Hi,

during the beginning of our installation (OnFirstUIBefore) we are running the UseDLL function with a dll that is apparently depended on msvcr.dll. the function fails to load the dll on OS that are older then vista, and in this case we must install Microsoft Visual C++ 2008 Redistributable Package (x86). how can this be done as part of the installation before we call the function? this is a non MSI project.

thanks,
Dana

Can you use static linking for the DLL to avoid depending on the runtime dll?

Hi,
No, must be dynamic...
Any other solutions?

thanks,

This runtime is deployed as a side-by-side assembly on XP and upwards. This has a lot of implications for how dll's are loaded and where they are loaded from - too complicated to go into detail here. What you can try, is to copy the msvcr.dll into the same directory as your other DLL (also copy any additional dependencies - use dependency walker to determine). The system wide side-by-side version of the runtime will still be loaded on XP and above - if available - regardless of any local copies of the dll in the application folder (unless measures are taken to prevent this).
