Support for W8.1 will mean 64bit, won't it?

It would probably need a good deal of regression testing at the least. You may also find that:

• some elements of the application and/or its libraries are hard-coded for 32-bit
• some behaviours that expect 32-bit (such as integer size) behave incorrectly under 64-bit operations.

Possibly. But necessarily?
