RW Interactive QRS Access

Install QRS Access

This is the install page for RW Interactive’s access app. You need a personal invite code to download.

Enter your invite code to unlock the download. You can read the steps below right now.

Twelve characters, from the email you were sent. Case does not matter and the dashes are optional. 0, O, I, 1 and L are never used, to avoid confusion.

This app is internal and is never code-signed. Your operating system will warn you that the publisher is unknown — that warning is correct. The SHA-256 check in step 3 is what proves the file is ours.

JavaScript is off_ Without JavaScript all six steps appear at once, for every system this release offers, each with its own checksum. The download unlocks when the server accepts your code — the server is what checks it, not this page. Nothing is withheld; it simply is not revealed one step at a time.

Which system are you on?

▲ Why your system warns you

RW Interactive does not sign this app, by deliberate choice, so your system cannot tell who published it. The warning is correct and will appear every time. The SHA-256 check in step 3 is what proves the file is ours — it is the only guarantee there is, so do not skip it.

Sign in

It opens your browser at the RWI sign-in page. Use the account whoever invited you created for you. If the page does not open, copy the address the app shows you.

Check that you are connected

The icon sits in your system tray. That is how you read the state:

Not connecting? Reply to whoever invited you's email — troubleshooting help lives inside QRS Access, not on this page.

Already have QRS Access installed?

Updates come through the app itself once you are connected. You will not need this link again.
