Camsoft’s USB dongle key security uses older RockUSB drivers. On occasion, the driver that the Camsoft installation installs, gets updated by windows automatically or by the user unintentionally. The newer RockeyUSB4 and Rockey4 drivers that windows installs, can cause problems for the software security feature. Sometimes, the new drivers do work with the software and sometimes on some Windows systems, they fail with our software. The exact cause is undetermined. The solution is to remove the new drivers and make sure that only the driver which is installed by Camsoft’s installation is the one being used.

- Open up a windows explorer window and navigate to the c:\windows\inf folder.
- Search for the oem(n).inf and .pnf files. Open up each oem(n).inf file using notepad to determine if it is the file for Feitian by examining the contents. Once the correct files are found, delete them.
- Navigate to the c:\windows\system32\drivers folder.
- Search for and delete the files named rockey4.sys, and rockey4usb.sys.
