I have a simple dll that is being injected into a target process using MS detours. The process doing the injecting is C# .net application.
Both the DLL and the detours library have been statically linked (/MT option).
However when I try to inject the dll into a target program on a client’s machine I get error “msvcr100.dll” is missing” error. Now I open the dll w/ depends and there is no dependency on “msvcr100.dll”.
Even weirder this issue only happens when the client is vista x64 or windows 7 x64. The dll is successfully injected on windows xp x32 and windows 7 x32 systems.
Any ideas on what bug in visual studio is indicating a dependency on a library not being used?
On edit:
Looks like someone else had the same issue … never resolved.
Compiled .dll files requiring msvcr100.dll to load
For the record installing Visual studio 2010 C++ redistributable on client machine “solves” the issue however I hoped to avoid that dependency by statically linking.
So I never did discover exactly what the issue is but on a hunch I tried running the application (exact same build w/ mscvr100.dll error) on another Windows 7 machine and it worked fine.
I reinstalled Windows 7 on the “problem” machine and the same build works fine without error. In my google searching I came across a report of another person having this issue after uninstalling Visual Studio. I know for a fact that Visual Studio was installed on the “problem” Windows 7 machine at one time and was currently uninstalled.
If this happens to someone else I would recommend try running the binary on a machine that has never had visual studio installed. If it works without issue then likely there is some issue related to VS uninstall.
