Unity 4.5 and Blender 2.7.1 don't work together?

I was getting pretty frustrated trying to get Blender 2.7.1 to work with Unity today. I brought models into Unity and it gave me the “Blender could not convert .blend to FBX” error. I eventually went back to Blender 2.7.0 and it works fine, but can someone tell me if it’s just me and my computer that can’t have them work together or if everyone is experiencing this? Thanks!

It looks like this issue can be fixed by replacing one of your python dlls.

Documentation and downloads are available here on the blender bug tracker

What is failing in this case is the python FBX exporter, as KellyThomas says, you can go to the Blender bug tracker and manually update the python core dlls, or use the FBX exporter directly from the “Export” menu in Blender. From Unity point of view, both solutions are exactly the same, as Unity is actually reading a .fbx file, and not a .blend file, that’s because when Unity detects a .blend file in its Assets folder, immediately calls Blender “asking” for a .blend conversion into a .fbx, so Blender uses the python files to do the exporting requested.

Thank you all for your answers! I should have checked back on this sooner, as Blender 2.7.1 is outdated now with Blender 2.7.3. Thanks anyway!
