It works. The only problem is report of the crash on close application. There is no problem to have 2 PSPads together and 64b version use for large files only.
I will try to find reason of this behavior. It's based of compiler, not the source code. Source code is same. -- <https://forum.pspad.com/read.php?4,78088,78136> PSPad freeware editor https://www.pspad.com
