Update/Remove driver

  If you have a problem with a protected application, please use the SF Helper utility. It will help you to diagnose the problem and solve it faster.

Following information is only required for applications protected with driver. Remember - not all programs are protected with driver. A developer or a publisher of a program decides whether it is necessary to apply protection driver for the application, depending on the required protection level.

How do I know whether my program uses protection driver?

  • If a message about driver installation is displayed at the first start of the protected program, then the driver is used.

  • Protection driver update does not affect the whole protection version installed on the program.

With so many various hardware components and software for personal computers, the StarForce specialists improve the protection driver constantly and make it compatible with newly released programs and operating systems.

If you have problems with running a protected application, driver update can solve the problem in some cases, as well as it can improve the interaction between the protected application and the drivers in programs from other vendors.

There are two ways to update the driver; these methods depend on the current version of protection installed for the software in use.

How do I know which protection version is installed for the application I use?

1. Version 5.5 and higher:

In version 5.5 and higher, the most common operations (such as driver installation/removal, driver update check and download) are performed using Graphical User Interface (GUI) of the executable file of the protection system. The file can have any name as specified by the publisher. It is usually PCNSL.EXE for latest protection versions and PROTECT.EXE for earlier versions. This file is in the root folder of protected application.

GUI of pcnsl.exe.
