Drivers for DESkey (dongle) software.
Software licencing is now managed by internet activation and USB dongles are no longer used. The following relates to older versions of the software that still use USB dongles.
If you need to delete existing DESkey (dongle) drivers, for example before loading a new version of CPO, then search for the files dk*.dll and delete them.
The DESKEY32.dll dynamically linked library is normally installed as part of the normal installation process. If it seems to be absent then it is possible to manually install the drivers that support the dongle by going to the web page :
and downloading and installing the dk3 driver. This is the driver that is included in the CPO installation disk. You might also have to download the latest software if you change to a later OS, such as Windows 7.
