When trying to connect to the license server I get an error-message saying: Warning: License file is using unknown/invalid syntax”.

Answer 1: The incorrect version of the licenser server is installed (for example the license server for SIMCA 13 is installed while you have a license file for SIMCA 12 or the other way around.) Make sure you have the correct license server installed

Answer 2: You have received an incorrect license file (for example you have received a license file for MODDE 9.1.1 while you should have a license file for MODDE 9.1.) Please contact DAS_register@mksinst.com to get the correct license file. In this email please make sure the following information is available; your name, company/department, site, activation key/product key, registration key and information about the error.
