When you first run the software on a new hardware there is an activation dialog box. In order to activate all features of the full version you should activate your registered copy of the software. Free Edition contains a demonstration version of the activation procedure. You can activate your copy via direct Internet connection or you can obtain activation key on the software sites.
Press the button "Activate via Internet". If it is possible to connect to the Internet from the software directly then activation will be proceeded automatically. Activation key will be saved to the software folder.
If Internet activation does not work you may obtain activation key manually
in three steps.
1. Run the software on a computer where you want to activate it.
Press the button "Activate with Activation Key/File".
Write out your Prod.ID and Inst.ID.
2. Visit one of the software activation sites from anywhere. Enter your
Prod.ID, Inst.ID and registration e-mail in the corresponding
fields. An activation key will be generated for you. Save it.
3. Run again the software on a computer where you want to activate it
and enter your activation key. The activation completes.
Instead of manual writing you Prod.ID and Inst.ID
you may save them to the file dmdeinst.dat on the first
step and then upload this file on the activation site on the second step.
Also you may save your activation key from ths site to the file dmdekey.txt
on the second step and open this file on the third step
instead of typing your activation key manually.
