• The HTTP link for the Terms of Service isn't yet operational.

Will work once merged

• I haven't verified if installing a new version of MS requires re-acceptance of the ToS.

When the user accepts it the first time, we create an empty file, so next times the installer is ran (for example, for an update), we check if this file exists or not: https://github.com/massalabs/station/pull/1244/files#diff-4bc1993c44b0052596d7cbce5d4d3082232197d6c3fa2437af8385ca92d5d860R39-R45

If it already exists, that means user already agreed so we don't need to ask again

I know, but I haven't tested it :-)
