A lower software version may be run using a higher version license (please see the specific examples below). See the version specific examples below. This may require creating and using a text file named level.txt within the installation folder of the earlier product version.

On this page:

To create a level.txt file, create a text file with the Product Level and Product Version of the current license (please see examples below for exact specifications). Rename the file as level.txt and copy into the location listed below.

Location of level.txt file

Standalone license – For a standalone license, the level.txt file should be located in the lower version program folder, which contains the program executable (*.exe). The license file ('lservrc' file) of the current version should also be copied into this same folder as the level.txt.

Network license (with full product installation on client machine)– The level.txt file should be located on the client machine in the lower version program folder, which contains program executable (*.exe).

Network license with workstation installation on client machine – For a workstation installation, the level.txt file should be located on the server in the lower version program folder, which contains program executable (*.exe).

NOTE: This process may not work when versions are separated by more than one major release, in which case the license file for the older version should be requested. It is not possible to run V15 using V16 license, because the licensing system has changed between program versions.

Running CSiBridge v21 using a CSiBridge v22 license

When running CSiBridge v21 using a CSiBridge v22, the level.txt file created will contain one line with the following information:
