After the activated softlock license, student license, or trial version has worked for a few days, it cannot be started due to a license problem. On some computers, the message 'Virtual Machine Detected' appears.
What is the cause of it?

Answer

If a real computer with the Windows operating system is actually used and no hardware changes and/or new installation of the operating system has been made, the license problem is usually caused by the following points:

  • The mandatory service 'Sentinel LDK License Manager' may be damaged after a Windows update.
Solution: Reinstalling the driver. It can be downloaded and installed via the following link. http://download.dlubal.com/?file=Sentinel_LDK_GUI_setup.zip

  • The antivirus program blocks the file hasplms.exe.
Solution: Add the hasplms.exe from the directory to the exceptions of the antivirus program

  • Other security software (e.g. Sandboxie) prevents proper communication of the license service.
Solution: You can also either add hasplms.exe to the trusted programs or uninstall this software
