Starting Dongle Software

The SenSoft package uses a dongle to protect the license.  This is emulated in software, and the dongle emulation needs to be turned on after a reboot.  If it is not turned on, you will see an error message.  If you did not start the dongle software, and you select the blue SenSoft icon, you will see "Protection dongle not found." screen.  Click OK and start the dongle software.


Select the "Shortcut to Wkpe.exe" icon.  It is the black IC chip lower left on the desktop.  You will see this window next.




Select File and then Open, you will see this dialog.  Highlight the only filename, SPOTDONG.kpe, and click on the Open button.



This loads the dongle contents into the emulator.  Now, select Function and "Enable Emulator" as in the next screen.


Collapse the window and leave it running in the background.
