Error message under installation or under Change of installation:
"The source folder is not versioned properly: C:\Users\username\Downloads.
If you copied this folder manually, you may have forgotten to copy the
swdata99.id or swdata1.id files which identify the version of a download or
DVD folder, respectively; or the file could not be written."
To resolve this issue:
- Create a .TXT file in the location mentioned in the error message.
- Edit the content of the file. The content must be: SOLIDWORKS 20XX SP0X
(change to installed version and service pack. E.g. SOLIDWORKS 2021 SP03)
- Name the file: swdata99.id (remove the .TXT extension and replace it with .id)
- Continue the installation.
