Adding support to 64 bits from 32.

Job ID: 32857406

Budget: $30 – $250 USD

I have an application made for 32 bits. Now I would like have 64 bits support.

The code is *.asm and is compiled under fasm.

Can you help me convert/adding support for 64-bits support.
I would like future communication under TEAMS(microsoft)

Under the progress, I require daily, small, efficient communication between you and me if else nothing else is decided between us.
