Update and Uninstall

Update and Uninstall

Both flows ship as standalone single-file exes that live next to WKVRCProxy.exe.

Sources:

• src/WKVRCProxy.Updater/Program.cs — WKVRCProxy.Updater.exe
• src/WKVRCProxy.Uninstaller/Program.cs — WKVRCProxy.Uninstaller.exe
• .github/workflows/release.yml — produces the zip the updater consumes

Update (WKVRCProxy.Updater.exe)

No flags. Running it is the request to check-and-maybe-update. Behaviour:

1. Reads the watchdog's FileVersionInfo to determine "current version".
2. GETs https://api.github.com/repos/RealWhyKnot/WKVRCProxy/releases/latest.
3. Parses the tag, strips the leading v, parses as System.Version.
4. If the remote isn't newer, prints You're on the latest version. and exits.
5. Otherwise prompts: Update available — install now? [Y/N] (auto-N in 15s). Times out as No if the user is AFK.
6. On Yes:
   • Closes the running watchdog (CloseMainWindow → Kill after 5 s).
   • Downloads the .zip asset from the release assets.
   • Extracts to a temp dir, copies files over the install dir (skipping its own exe so it doesn't try to overwrite itself while running).
   • Relaunches the watchdog and exits.

Uninstall (WKVRCProxy.Uninstaller.exe)

No flags. No prompt. Running it IS consent. Behaviour:

1. Closes any running WKVRCProxy.exe (CloseMainWindow → Kill if needed).
2. Restores VRChat's yt-dlp.exe from yt-dlp-og.exe. Belt-and-suspenders: if the backup went missing, drops the bundled vanilla yt-dlp in place so VRChat still has a working yt-dlp.exe.
3. Re-execs WKVRCProxy.exe --remove-hosts-entry under runas to remove the 127.0.0.1 localhost.youtube.com line.
4. Wipes %LOCALAPPDATA%\WKVRCProxy\.
5. Schedules the install directory's self-deletion via a detached cmd.exe /c rmdir, so the uninstaller's own exe isn't locked when the directory disappears.
6. Prints a single completion line and exits with status 0 (or non-zero if any step had errors).

Failure modes worth knowing

• Hardcoded GitHub URL: the updater hits api.github.com/repos/RealWhyKnot/WKVRCProxy. If the repo moves, all installs need a manual update.
• Protected install location: installing under Program Files means the deferred cmd.exe rmdir runs without elevation and may silently fail to remove the directory. Document install-anywhere usage; the README does.
• UAC declined on uninstall: the hosts entry stays. The uninstaller prints a hint pointing to the manual fix; the leftover line is idle and harmless without WKVRCProxy running.
