Upgrading to Pro later

Same installer. Subscribe, then activate the copy you already have from inside the application — it shows you a code, you type it in here, and Pro switches on. No reinstall.

This build is not code-signed yet

Windows SmartScreen will show “Windows protected your PC” the first time you run it. That warning means Microsoft has not seen this publisher before — it is not a claim that anything is wrong with the file. To run it anyway, click More info and then Run anyway.

We would rather tell you that plainly than have you find out at the UAC prompt. An Authenticode certificate is on the way; when a signed build is published this notice disappears and the signature will be listed above. In the meantime, check the SHA-256 — that is the check that actually proves you have the file we published.

Installing

  1. Run the installer. It offers a per-user install by default, which needs no administrator.
  2. Launch LANWRX from the Start menu, under CompanyWRX.
  3. It reads your adapter and offers the network you are on. Press Scan.

Uninstalling

Settings → Apps → LANWRX → Uninstall, in the ordinary way. Your scan database is left in place so a reinstall picks up where you were; delete %APPDATA%\CompanyWRX\LANWRX yourself if you want it gone.

What happens when you press Scan

Recorded from the application, at the speed it actually runs.

A /24 — 254 addresses — swept in real time, with each device appearing in the table as it answers rather than all of them at the end.
