Thanks for the clarification Alex.
I installed DE (Pack File 7.00b (OS/2)) on a ArcaOS 5.0.7 VM (Just for testing). It installed, but it didn't show anything good. It changed the icons, that is the only thing I can see. I didn't find anything interesting (remember it was my first time using Dialog Enhancer '99). Uninstall worked perfectly so I had reverted back without issues.
So, I guess I will move on since I didn't find the useful thing on this software. But if someone is still using it, feedback is also welcome.
Thanks for the help and feedback.
Regards
