Install on Windows
Broken Toolkit ships Windows apps as signed MSIX packages. Because we sign with our own certificate rather than a Store account, Windows needs to trust that certificate once before it will install anything. Do steps 1 and 2, then install whichever apps you want.
Turn on Developer Mode (or not — see the note)
Open Settings → System → For developers and switch on Developer Mode. This lets Windows install MSIX packages that aren't signed by a Store certificate.
Prefer the certificate route? Step 2 alone is enough. Installing the certificate means the apps work even with Developer Mode off, and gives you a cleaner "trusted publisher" label instead of the unknown-publisher warning. Do both if you want the least friction.
Install the Broken Toolkit certificate
Download the .cer below, then double-click it → Install Certificate… → choose Local Machine → Trusted Root Certification Authorities → Finish. You'll be asked to confirm; say yes. You only do this once per machine.
Or do it silently from an elevated PowerShell window:
Import-Certificate -FilePath "$env:USERPROFILE\Downloads\broken-toolkit-cert.cer" -CertStoreLocation Cert:\LocalMachine\Root
Heads up: our certificates are self-signed, so Windows will warn that you're installing a root certificate. That's expected for sideloaded builds. Only install it if you trust Broken Toolkit — you can remove it later from the same Trusted Root list.
Pick an app and install it
Download any .msix below and double-click it. Windows will show the app's publisher as Broken Toolkit and install it. If you'd rather not click around, there's a one-liner for that too:
Add-AppxPackage -Path "$env:USERPROFILE\Downloads\tvremote-windows.msix"
Windows apps
TV Remote
v0.9.1.0Universal remote for Roku, Fire TV and Android TV. D-pad and touch, one screen.
Broken Toolkit Updater
v0.9.0.0Checks the feed for new builds and installs verified APKs. Also manages your own sideloaded apps.
BoredGames
v0.2.0Ten public-domain board games, fully offline, with LAN pass-and-play. .NET runtime is bundled.
SSH AI Terminal
v0.2.11.0Offline SSH client with an optional on-device AI assistant and biometric app lock. Flutter runtime is bundled.
Every app above is signed with the same Broken Toolkit certificate except BoredGames, which uses our Store publisher identity — install that app's own .cer too. They don't conflict; Windows trusts both once imported.
If something goes wrong
"The certificate is not trusted" or error 0x800B0109
The certificate isn't installed. Redo step 2 and confirm you picked Local Machine → Trusted Root Certification Authorities, and that you answered yes to the security prompt. You need admin rights for that choice.
"App installation failed with error 0x800B010A"
Same cause, different code — a self-signed root that isn't in Trusted Root. Note this is expected even for a correctly signed package: Windows can't validate our certificate chain on its own. Import the certificate and retry. The package signature itself is valid.
Windows SmartScreen says "Windows protected your PC"
SmartScreen flags anything outside the Store ecosystem that it hasn't seen before. Click More info → Run anyway. This is normal for a first-time sideload of a new app; the warning stops appearing once Windows has seen the package.
I'm on Windows 10 or 11 in S mode
S mode blocks sideloading entirely. Use a normal edition — Developer Mode and MSIX installs aren't available in S mode.
How do I uninstall?
Settings → Apps → Installed apps, find the app, uninstall. The certificate is independent of the app, so it stays installed — remove it from Trusted Root if you want it gone.
