11 years ago ASSIMP does not support vertex keyframes (only bone animation is supported). The library reads only one frame of models with vertex animations. By default this is the first frame.

Assimp Viewer is a DX9-based model viewer, it doesn't support animation though.
To build it in vc9, click assimp--3.0.1270\workspaces\vc9\assimp.sln Recommend configurations are debug-dll and release-dll, since the code size is very huge, 100M+ IFC (.ifc, Industry Foundation Classes) is not necessary for game dev/creative coding, it's fine to remove it.
