Installing Overwolf into a Proton / umu-launcher prefix on Linux (no Steam)

Getting the Overwolf client installed into a Wine/Proton prefix driven by umu-launcher, without Steam. The normal Overwolf web installer fails inside Wine; this is the route that actually works.

What you need

• An existing Proton prefix to install into. If you came here from a Warframe/AlecaFrame guide, that's your game's prefix. Otherwise any umu prefix works — you can make a throwaway one by running

Running AlecaFrame (Overwolf) with Warframe on Linux — non-Steam, umu-launcher + Proton

Goal: Get AlecaFrame — a Warframe companion app built on Overwolf — to actually read live in-game data (inventory, relics, missions, etc.) when Warframe runs on Linux through umu-launcher + Proton, without Steam.

What this achieves (verified working):

• ✅ AlecaFrame's data/tracking works — inventory and the rest populate from the live game.
