[Setup] Support per-user installation · Issue #15516 · microsoft/PowerToys (original) (raw)

Description of the new feature / enhancement

Moving to a full per user proved to be not so simple. This issue tries to have a comprehensive list of issues with it:

• Cannot uninstall previous versions w/o elevation, since accessing locations like Program Files isn't possible with limited privileges. Looks like the least awkward solution is to employ elevated WiX bootstrapper for this somehow.
• If Product is switched to perUser, WiX start requiring using explicit registry keypaths as well as explicit RemoveFiles elements, and those do not properly support downgrading and upgrading to a different install directory. We might try removing explicit Id/Guid for Components, also that'll likely resolve infamous missing app.dark.png class of issues.

Scenario when this would be used?

• some environments disallow elevation
• installation is more contained and cannot interfere with other users
