1. Hi all! Just found a rare unique dfd 4.24 copy but LegEasy4DOS Professional ver. 1.4.0.4438(20) Released: 07/01/20 asks for license key and offers  no trial period too. Please help. Glory to DataEase team nevertheless!
2. hx

LegEasy 1.4.0.4438(20) offer a 30 day free trial period for new users. 

After the 30 day free trial one will need to purchase a valid license.

We assume that L4D has been used on the device in question previously?

I've recovered my ancient IBM SCSI disk by means old AHA-2490 AU device on modern PC yesterday. My vintage IBM tower & motherboard with SCSI port on it died due to frequent blackouts before. So I got software from it and planned to use L4DOS to bypass absense of Evdat1.sys and Evdat2.sys (protection from evmove) ...an got message about license issue. I tried L4d years ago to test it wit de4.53 ///so I can't state that I have used L4Dos during a long period. So is the story. Is it possible to test dfd 4.24R with L4DOS just now ?

so

I was member of the team made enterprise management system on DataEase for this plant which was destroyed this month. The rar file is from that project.

Sorry, misunderstanding. It should now be working!

no problem. yes! it works! Glory to DataEase team! Thank You very much.

as to my de42.rar file attached..is it possible to run this dfd 4.24R with L4DOS ? the situation here needs to use this de4.24R official release from DataEase (Trumbull) of 1990s.. bought in Kiev (Kyiv) via Tamara Korinkovskaya (Oracle Ukraine later)

You can use your own DataEase in L4D so go for it. 

thank You! but there is no de16m.exe in de42.rar file...

use dease.exe

what are other ways to bypass protection caused by using evmove Evdat2.sys Evdat1.sys ? Thank You !

may be to restore installation copy ?

thus, dataease.exe instead of de16m.exe didn’t solve the problem nevertheless.

 But the negative result is the result too. Thank You.

Rename it to de16m.exe then

Why do you want to use this version. We all know that 4.53 is a far more superior version. There isn't one reason in the world for using 4.2

the only reason is to be ready for de4.24U ;) for I know where is that eclectic ukrainian version from Trumbul. Localization technology was by recompiling of general version using text files got from Kyiv.

renaming of dease into de16m helps nothing for problem is related to Az-Tech Software, Inc. Everlock.. theoretically renaming is useless in the case. But thx a lot .. nevertheless
