De-Registration can be performed in advance of moving software to a new computer or server. First download the de-registration files from the links below:

Emission Master De-Registration File
Emissions Accountant De-Registration File

Run Emission Master or Emissions Accountant. Then execute the Tools \ Run Script File menu command. Browse for the DeRegisterEmaster.dbk or DeRegisterEmac.dbk file (depending upon the program to be de-registered). There will be a confirmation prompt. Confirm the operation. A success code will be displayed in a dialog. Make a note of the number. The entire dialog text may be captured to the clipboard via the [Ctrl][Insert] key combination.

If the software is to be moved to a new server (or new PC for a PC license) please transmit the success codes to us and we will reset the license activation server to enable a new installation.
