There is little we can tell you from that screenshot, because it lacks
information. The error you are getting usually stems either from the
fact that OSG is unable to find the required plugin to load the data
file at runtime or that the plugin didn't load correctly (bad DLL,
bad/missing dependency of that plugin DLL, etc.)

Generally, Dependency walker complaining about dependencies of
Microsoft's DLLs (OpenGL32.dll in this case) is a red herring - those
messages you can ignore.

However, one message stands out in that Dependency walker - "Modules
with different CPU types found".

That means that you are mixing 32bit and 64bit DLLs in one program.
That is not allowed and will not work. Unfortunately Windows is
severely retarded in this regard and will happily load a 32bit DLL
into a 64bit program, only to crash later. E.g. Linux will complain
right away that it didn't find the correct DLL/shared library even if
the one for the wrong architecture is available.

Did you use 32bit dependencies (libjpeg) to with a 64bit version of OSG?
