For your testers: open a link, accept the NDA, install, update and play.
Windows may show “Windows protected your PC” because the beta installers aren't code-signed yet. Choose More info, then Run anyway, and only for files from www.mulno.com or updates.mulno.com.
The Launcher is sent on request
Until our update host's download links are open, we send the Launcher installer and SHA256SUMS.txt directly, and their buttons open a mail asking for them.

1 · CHECK THE DOWNLOAD
It must match the line for that file in SHA256SUMS.txt. If it doesn't, don't run it; tell us at security@mulno.com.

Microsoft Defender SmartScreen prevented an unrecognized app from starting.
Studio, the Launcher and games aren't code-signed yet: a deliberate, temporary choice until our first paying customer. The hash is how you know the file is ours.
Studio 0.4.2, the Launcher 0.1.3, the Unity package 0.4.1 and the Claude Code plugin 0.4.0. Everything in 0.4.1 still works the same way. The Unity package, the capture DLL and the uploader are one unit: replace the whole package and rebuild your playtest player.
Studio, the Unity package and the Claude Code plugin now download from the Downloads page in the web app, after you sign in. The Launcher stays a free download for your testers.
Studio 0.4.2 asks you to sign in once, in your browser, and then checks for updates with your account. Studio 0.4.0 and 0.4.1 can't find 0.4.2 by themselves: install it once from your Downloads page.
Nothing changes for testers. A Launcher 0.1.2 offers the update when it starts.
