Title: vMix GT Title Designer – "License not found" error
Body:
Has anyone else run into a "License not found" error when trying to use vMix GT Title Designer? Confirm purchase/entitlement
I have a valid vMix Pro license (or 4K/HD – adjust as needed), but the GT Title Designer keeps telling me the license is missing.
What I've tried so far:
The GT Title engine works fine inside vMix itself, but the standalone GT Title Designer app refuses to recognize my license.
System info:
Any ideas? Thanks in advance!
This is a specific quirk of the GT renderer. The licensing check sometimes reads your primary graphics adapter’s serial number. If vMix switches between your Intel iGPU and your NVIDIA/AMD GPU, the Hardware ID changes mid-session.
Temporary Test:
The GT Designer requires access to license files stored in protected system folders. If vMix doesn’t have permission, it can’t verify the license.
Fix:
Permanent fix: Go to shortcut > Properties > Compatibility > Check "Run this program as an administrator."
The "License Not Found" error is almost always the result of having a "4K" level tool trying to run on an "HD" level installation, or an outdated Title Designer tool trying to validate against a newer vMix version.
Once you align your software versions, the error should disappear, and you can get back to designing stunning overlays for your stream.
