We found a crash in Havok Preview Tool 64-bit 2011.3.1.1
We apologize if this has been fixed in the latest version.
The attached file will crash HPT 64-bit. However the 32-bit version can load it fine.
The 64-bit version will say "hkp Key Code is invalid or is for a diffeerent product version" and dump a very long call stack.
Steps to reproduce:
Create two capsules as separate rigid bodies, one should have a mass (very important!) the other may or may not have. Now these capsules must start in a colliding state. Export it (filters used: Create Rigid Bodies, Write to Platform)
Watch previewer crash.
If the capsules don't start in a colliding state (i.e. separate enough from each other) or both have 0 mass, the crash will not happen.
