Frequently asked questions
Licensing, activation, compatibility and installation for ZeroFX products.
How many computers can I activate?
One license can be activated on up to three computers at the same time. A license is personal and may not be shared with other users.
How do I move a license to another computer?
Deactivate the product on the old computer, then activate it with the same key on the new one. If the old computer is unavailable, contact support and we will release the activation.
Which platforms and plug-in formats are supported?
GrandTwin, GrandGate and GrandCab run on Windows 10/11 (64-bit VST3) and on macOS 12 or later (VST3 and Audio Units, Apple Silicon and Intel). One license key works on both systems. AAX is not currently supported.
Where is the plug-in installed?
On Windows the installer places the VST3 in the standard system plug-in folder. On macOS it installs VST3 and AU to /Library/Audio/Plug-Ins. Refresh or rescan your plug-ins in the DAW after installation.
Can I try the products before buying?
Yes. Demo installers are available on the Downloads page so you can verify compatibility and workflow before purchasing.
What is included in the Guitar Bundle?
GrandTwin, GrandGate and GrandCab — three separate products with three separate license keys. The bundle costs the same as two products. If you already own one of the plug-ins, use the upgrade option in the Guitar Bundle section on the home page and pay only the difference.
Is the license perpetual?
Yes. It is a one-time purchase with no subscription. Updates within the purchased major version are included.
How do I contact support?
Email support@zerofxaudio.com with the product name, your DAW, your Windows or macOS version and a short description of the problem.
