If you're using 3ds max to try to do augmented reality using FlarToolKit  in flash you MAY have run into an error 126 when trying to install feeling softwares 3.05c version of ColladaMax

this error 126 where the DLE file fails to initialize has to do with the directX SDK not being installed. This will happen on the stock 32-bit version AND the modified 64-bit version.

There's not really any documentation that will let you know this, and you'll probably waste a few days trying to figure it. That's what I just did unfortunetly. 

Hopefully this will help. download the below 2 files and install them. After that collada export is smooth sailing.

the built in autodesk collada DAE export works OK, but it mostly sucks and gets texture mapping wrong.
