A lower software version may be run using a higher version license by creating a text file named *level.txt* in the installation folder of the earlier product version. For a workstation installation, the level.txt file should be located on the server with the executable. For a standalone installation, the level.txt file should be located in the program folder with the executable.

The text file should have two lines, described as follows:

* *Line 1: Product Level*. Depending on the product level, enter 'Basic', 'Plus', 'Advanced', or 'Ultimate'.

* *Line 2: Product Version*. Enter only the version number of the current license, for example, '15'.

When using a standalone version, the license file of the current version should also be copied into the installation folder of the previous version.

*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.
