We don’t currently have a 64-bit build of the Scaleform Unity Plugin. We do have a the full version of Scaleform in 64 bit.
Do you have any plans to create a 64bit version of the Unity plugin? We are trying to get our game to work on Unity 5, which is a 64bit application, and the lack of a 64bit Scaleform plugin is preventing us from doing that.
Unfortunately, the post in that thread wasn't meant to express triviality with regards to the conversion to 64-bit.
It is a non-trivial series of changes which must take place as data is marshalled between C++ and C# code across several platforms.
As mentioned in that thread, developers have the option of purchasing a source license and working on a port themselves.
