GoKawiilNix flake packages Microsoft 365 to run on Linux via umu-launcher and GE-Proton
A newly published Nix flake automates installing Microsoft 365 (click-to-run Office) on Linux without a virtual machine, using the umu-launcher tool alongside GE-Proton, the gaming-focused Wine build from Valve and GloriousEggroll, with Bottles' ProtoSoda Wine core offered as an alternative runner. The project doesn't bundle any Microsoft software itself; instead its ms365 script fetches the Office Deployment Tool and Office files at install time, requiring users to supply their own Microsoft 365 license and sign in. The approach builds on prior community work, including Bottles' reports of Office 365 running on Wine and older ruados/eylenburg registry and DLL tweaks.
