[wix-users] Getting JSON Settings File to Survive Major Upgrade

[Rob Mensching]

Easiest solution: Read settings (if they exist) very early, write settings out always (new or from previous install).

Surviving Major Upgrade but still disappearing at the end of use seems like a tough challenge.

I've got a bad solution.
On uninstall register a RunOnce action to delete the files/folder.
On install remove any such RunOnce entry.

I'm probably wrong, but I've always consider major upgrade just an uninstall->reinstall with some installer settings migrated across. So this would survive such a process.


There's likely a better solution though.
