But you created it so you would have 3D somewhere. If you need to run it on today's machines you can install Virtual Box (free) and some version of Windows in Virtual Box and finally put your old KeyCad 3D in that Windows.
If you sold/lost your CD well, you hunt on ebay, etc.
I lost my keycad 3d program and after several years i need to open files that i created with keycad 3d. i try to get the software but i do not find it, there is keycad 2d but no 3d.
Please sombody help. it is an old software i know but i need my files recovered.
