Updating your license file
FlexNet Publisher
To replace the Siemens Licensing file, run the licensing installer for the currently-installed version and select the option Replace License File. The installer puts the old license file inside the license_backup folder.
Note
If the license file is for a new version of the application program, you should install the new license server software.
