Inno Setup 6.2.2 (pinned because innoextract 1.9 in Debian trixie
can't parse 6.3+ headers) doesn't recognise the 'x64compatible'
keyword. Use the legacy 'x64' which works across 6.0-6.7.
Failure: 'Error on line 25 in installer.iss: Value of [Setup]
section directive ArchitecturesAllowed is invalid' (run #11).
