The primary hurdle users face is that APS Designer 4.0 is a 32-bit (or even 16-bit) application built for Windows 95, 98, or XP. Windows 10 64-bit has largely dropped support for older 16-bit installers, and even 32-bit applications can struggle with driver signatures and system permissions on modern OS architecture.
If you are looking for a "native" Windows 10 version, you will be disappointed. APS Designer 4.0 is abandonware—it is no longer developed or officially supported by the original creators. Therefore, there is no official "Windows 10 64-bit" edition. However, you can still run the original version using compatibility modes or virtualization.

Fix: You likely forgot the compatibility mode. Re-apply Windows 7 or Windows Vista compatibility to Designer.exe. Also, disable full-screen optimizations in the same compatibility tab.
Once installed, apply the same compatibility settings to the main executable (APS.exe or Designer.exe) inside the installation folder. Set it to Windows 7 mode and Run as Admin permanently.
