If your software isn’t listed, you can’t re-license after you delete adskflex files, and your software will stop working. You can then safely delete adskflex files. First check whether your older version of Autodesk standalone licensed software is listed in Transport Layer Security (TLS): Updates Required to Maintain Software Access. Important: if you have a standalone perpetual license, deleting the adskflex_#_tsf.data file can cause your software to stop working.
Skip this step if you don’t have licensing issues.
Go to the Windows TEMP folder by entering %TEMP% in the Windows Run box and delete all the files in that folder.
