Stream to 3D Licensing and Activation

Updated 18 July 2026

This page covers the most common licensing/activation issues and what to do next. If you see an LVE0xx code, also check Error Codes (LVE0xx).

How licensing works (high level)

Stream to 3D checks that your purchase and feature access are valid.
An internet connection is required for licence, subscription and feature checks.
If you see an “Update Available” message, update to the latest build for your store/edition before troubleshooting further.

Store differences (Steam vs Gumroad/Itch/etc)

Steam

Steam builds use Steam entitlements for licensing (you typically don’t manually enter a license key).
If Stream to 3D prompts for an unlock/re-check, use the in-app Refresh action (when offered) and ensure Steam is running and up to date.

Gumroad / Itch / other stores

Non-Steam builds typically use a license key provided by the store (often in your receipt email).
Some editions/add-ons may require an extra “Link” step (entering an add-on key) depending on where you purchased and what you own.

If you’re not sure what you purchased (or which edition/build you installed), start with Support and include your store and purchase details.

Live Sources feature access

Current purchases include PC Screen and Live Video Conversion to 3D. Some earlier Standalone purchases pre-date this capability and require the Live Sources feature upgrade before a PC screen, camera or capture-device source can be used.

Steam: purchase or obtain the add-on through Steam, return to the Stream to 3D unlock dialog and choose Refresh. Steam must be running.
Gumroad: paste the add-on licence key into the unlock dialog and choose Link.
Itch.io: paste either the add-on Download Key or the complete Itch.io download URL into the unlock dialog and choose Link.

After successful activation, Stream to 3D resumes the Live Source operation. If linking fails, check that the main product and add-on belong to the same store account, confirm the internet connection, and retry before contacting Support.

LVE022: follow the complete message

The appropriate action depends on the wording displayed with the code:

Installation limit: Stream to 3D licences allow installation on up to 3 machines. Release 5.5.1 and later should normally recognise an application reinstall on the same Windows installation, but reinstalling Windows or changing computer can still appear as a new installation. Contact support to review or reset the count.
Temporary Itch.io validation limit: wait briefly and retry. Contact support if the message continues.
Repeatedly uninstalling and reinstalling the application is unlikely to resolve either condition.

Connection errors (LVE023)

LVE023 means Stream to 3D could not complete a licence check.

Check internet connectivity.
Temporarily disable VPN/proxy/ad-blocking DNS if you use them.
Check firewall/endpoint security isn’t blocking Stream to 3D.
Retry after updating to the latest version.

Other common licensing codes

These codes are explained in detail on Error Codes (LVE0xx). Common examples:

LVE018 — missing key or machine registration mismatch.
LVE020 — license key does not match product/edition (wrong installer for the key).
LVE004–LVE007 — subscription ended/cancelled/failed/refunded (store/billing state).

Before contacting support

To resolve licensing issues quickly, include:

Your store (Steam/Gumroad/Itch/etc) and what you purchased (subscription vs one-time, edition name if known).
Your Stream to 3D version (and whether it’s the Steam build).
The exact error code/message shown (e.g. LVE022).
