How To Resolve ''Installer Payload Initialization Failed'' Error

If you get ''Installer payload initialization failed'' while trying to download or install our software, this means something on your system is blocking our authentication server.

There are two common solutions:

1) Use the full installer. You can find the full installer of the latest version to the left of the blue buttons on Topaz Labs Downloads Page.

If you have a previous version, please let us know and we can provide it for you. Some other common versions:

Sharpen AI 2.1.8 Full Installer For Windows

DeNoise AI 2.2.12 Full Installer For Windows

Gigapixel AI 5.1.7 Full Installer For Windows

Mask AI 1.3.4 Full Installer For Windows

Studio 2 2.3.1 Full Installer For Windows

Adjust AI 1.0.5 Full Installer For Windows

JPEG to RAW AI 2.2.1 Full Installer For Windows

2) If you have a program called System Mechanic installed on your computer, disable it and try again with our installer. In some cases, we have found that System Mechanic will block our software even while disabled and temporarily removing System Mechanic may be necessary to run the installer. So long as you obtained our installer directly from topazlabs.com or an email from Topaz Labs, your installer should be safe to run.
