I uninstalled 2019 Solidworks but when I try to download the new version I get the following error message:

The source folder is not versioned properly: C:\Users\Peter Anson\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


It looks to me like there is something hanging around from the old version that is preventing me from downloading but I don't speak computereez so don't really know what this means. I did have an earlier error message about an older version of Toolbox so tried deleting that folder so now I arrive at the new error message.
