Causes of License Problems for Softlock Licenses, Student Licenses, or Trials

After a few days of operation, the activated softlock license, student license, or trial version cannot be run due to a license problem. On some computers, the message "Virtual machine detected" appears. Why?

Answer:

If you are using a real computer with the Windows operating system and there have been no hardware changes and/or new installation of the operating system, the license problem is usually caused by the following:

  • The mandatory service "Sentinel LDK License Manager" may be damaged after a Windows update.
  • The antivirus program blocks the hasplms.exe file.
    • Solution: Add hasplms.exe from the directory to the exceptions of the antivirus program.
  • Other security software (for example, Sandboxie) prevents proper communication of the license service.
    • Solution: You can either add hasplms.exe to the trusted programs or uninstall this software.
