As this is not an official way of installing Arc, if you encounter any issues do NOT report them to the developers, they did not intend for people to be running Arc on Windows 10.
This works as of January 2022, in Windows 7, originally instructions for Windows 10, from a third party.
Open Admin Command Prompt and type these commands one by one:
rm %localappdata%\Spotify\Update
( Change rm to del in Windows 7, or delete manually )
mkdir %localappdata%\Spotify\Update
Recently found some clowny gist was the top result for 'google takeout multiple tgz', where it was using two bash scripts to extract all the tgz files and then merge them together. Don't do that. Use brace expansion, cat the TGZs, and extract:
$ cat takeout-20201023T123551Z-{001..011}.tgz | tar xzivf -You don't even need to use brace expansion. Globbing will order the files numerically:
$ cat takeout-20201023T123551Z-*.tgz | tar xzivf -
