## Activation

Attention! After buying the software you should download licensed copy from your personal section (restore address). Free Edition may not become fully functional. In order to enable all features you should activate the software when first run on a new/modified hardware.

Please use the software according to the license conditions in order to avoid blocking. Motherboard change, CPU change, or BIOS update imply hardware modification and require new activation (unless assigning to a removable device is used in Professional Edition). Reactivation on the same hardware is not considered as a new activation if it is caused by changing or reinstallation of operating system or by updating software. You may view your activation log in your personal section.

To activate on the same hardware you may use the keys stored in the work directory of the previously activated software copy. After support ends you may not activate the software another way.

### Activation via the Internet

Click `Activate via Internet`. If direct Internet connection is available the software will be activated automatically. Activation key will be saved to the software directory. DOS version does not support automatic activation via direct Internet connection.

### Activation Using the Activation Key

If Internet activation is not possible you may obtain and enter the activation key instead.
1. Run the software on a computer where you want to activate it. Click `Activate using Activation Key/File`. Write out your `Prod.ID` and `Inst.ID` (or save them to the file `dmdeinst.dat`).
2. Visit one of the activation sites http://activate1.dmde.com/ or http://activate2.dmde.com/ from any location. Enter your `Prod.ID`, `Inst.ID` and registration e-mail into the corresponding fields on the site (or upload the file `dmdeinst.dat`). An activation key will be generated for you. Write out it (or save to `dmdekey.txt`).
3. Run again the software on a computer where you want to activate it and enter your activation key (or open `dmdekey.txt`).

### Assigning Activation to a Removable Device

Professional Edition (for Windows 2K and higher and for Linux) additionally allows you to assign activation to a USB flash drive to run the software on different hardware without Internet access.

Initial Assigning Activation to a Device
1. Click `Assign key to device` (if the software is already activated then use menu `Help-Activation` before) and select removable device to be used for activation. The device must have correct serial number (12 or more digits and capital Latin letters).
2. Activate the software using any of the two instructions above (via Internet or using key). Assigned activation will be stored to dmde.ini.

Further Use on Different Hardware
Attach the device, start the software, and select the device in the list.

In the menu `Help-Activation` you can see if the software is activated.
