For faster help, tell us which part of the product you're using: the base app, the Streamer / VTuber mode, or a licensing issue.
Before you write
The requirements page and changelog answer the most common questions. A quick look saves a round trip.
Windows won't let me run the installer
That's the SmartScreen "Windows protected your PC" screen. Click More info, then Run anyway. The download page explains why it appears and how to handle it in Edge and Chrome.
I lost my license key / it won't activate
Write to support with the email address used at purchase. Activation failures are usually one of three things: an offline or firewalled network, an outdated app version, or a clock that's far off. Check those first.
How does the 3-day trial work?
From first activation you get 3 full days with everything unlocked. No card is required. The trial runs once per email address — see the Terms for details.
Can I move to a new PC?
Yes. Your license key is tied to your email, not to one machine permanently. Deactivate or uninstall on the old machine if you can, then activate on the new one. If activation refuses because the key is still bound, contact support and we'll release it.
Will it run on my GPU?
Check the requirements page for the GPU baseline and the VRAM budget — including the lean setup that runs the character on about 6 GB by moving models to external services.
What to include
- your OS version (Win10 or Win11, 64-bit) and GPU model;
- the KM Role Play version from the changelog or app title bar;
- one or two sentences on what you did, what you expected, and what happened instead;
- if the app crashed or froze, the app's log files — the app can save them to a folder, attach that folder to the email.
