Usually this is because the path of the file has changed (for example, it was initially installed on a mobile hard disk, but another hard disk was inserted, and the hard disk name E changed to F)
The solution is to find the path you installed before. In 2020, find the cad folder (the path you installed before) and move all the files to the path specified by the autocad shortcut.

Find the licpath.lic file.
For the 2020 version of the product, the Licpath.lic location is: C:\ProgramData\Autodesk\AdskLicensingService<product key>_2020.0.0.F
For 2017-2019 versions, the licpath.lic location is: C:\ProgramData\Autodesk\CLM\LGS<product key>_<year>.0.0.F
For example, for AutoCAD 2017, the licpath.lic file path is: C:\ProgramData\Autodesk\CLM\LGS\001I1_2017.0.0.F.
For 2016 products and previous versions, the licpath.lic location is C:\Program Files\Autodesk<program name>
