Once software is activated, some of the files are created to store license information.
The file created are *.41s, *.ent, *.key, *.rst with a file name "ddr".
After successfull activation you can create a backup of these files in a separate folder, in case the software installation goes corrupt or for any reason there is a requirement to reinstall the software then you can copy these files back to the {app} directory to restore the license from backup folder.
However you should keep these things in mind when you are restoring license.
a) It should be the same drive on which software was activated.
b) The drive is connected to same channel
If there are any changes to disk configuration the software would not activate with the backup license files.
