# Installation and Run

System Requirements Activation Languages Settings Limitations Updates

Attention! If in doubt about the physical health of the disc it is recommended to appeal to specialists. Further work with the disk (including starting up) may worsen the problem or cause complete inability to recover data.

Attention! Do not load operating system, install or run the program on a partition where lost or damaged data is located (data to recovery), otherwise it may be erased irrevocably.
To prevent writing to the problem disk it is highly recommended to load the system from the removable media (LiveCD, bootable flash drive).

To install and run the program just extract entire software package into a single directory (may be on removable media) and run `dmde.exe` or `dmde` depending on a version. You need Aministrator/Superuser priveleges to access devices in Windows NT+, Linux. To run the software without Adminstrator rights (to work with images only) add the parameter `notadmin=1` to the file `dmde.ini`.

## Operating Systems

### Windows 98/ME

Attention! Without special patches Windows 9x/ME handles 128 GB and larger drives incorrectly.
To avoid the problem reload computer in MS-DOS mode and use DMDE for DOS to access such drives via BIOS or ATA-interface or load another OS.

### Windows 2K/XP

To use the program you should login as Administrator.
Attention! To work with 128 GB and larger drives you need Windows 2K SP4 with LBA48 support manually switched on in the registers or Windows XP SP2 (LBA48 is switched on by default).

### Windows Vista/7/8

To run the program as Administrator right-click the program icon and use the corresponding command in the context menu or confirm UAC elevation request.
Attention! To work with drives larger than 2 TB under Windows Vista/7/8 the most recent versions of controller drivers must be installed.

### Linux

At first go to the Root Terminal or run Terminal emulator (Konsole, Gnome-terminal, etc.). Go to the software directory and type `./dmde`. You should run the software as a superuser to access devices. Please, refer to your operating system documentation for this information (e.g., run `sudo ./dmde` in Ubuntu, go to root with `su` command in Debian at first, etc.). You may also need to set execution permission for the file `dmde`.

### DOS Bootable Disk

Prepare any bootable DOS disk (flash disk) or a diskette. You may format such diskette under Windows using option "Format bootable MS-DOS disk".

If there is not enough space to extract the software package you may copy not unpacked distribution to the root of the disk. Along with this extract and copy files from the `DOS boot package` which is designed for automatic unpacking and running DOS distribution. After start up just run `dmde.bat` or if you wish the software to start automatically just rename `dmde.bat` to `autoexec.bat`.
