Choose the package for your computer
ConsoleTuner lists separate Windows and macOS packages. Its Windows page also links a legacy 32-bit build, separate from the main 64-bit download. Choose the main package unless you have a specific need for the older architecture. Read the operating system line on the manufacturer’s listing instead of inferring support from the package name or from a third-party download site.
Gtuner Pro is listed separately for Titan One. If you are looking for the desktop application that programs Titan Two, use the listing labeled Gtuner IV. The two programs serve different hardware and their download names can be easy to confuse.
Prepare and launch the desktop app
On Windows, extract the downloaded archive to a folder before launching the executable. The Gtuner IV maintainer calls out that step for startup failures. Keep the extracted files together so the application can find the components supplied with it. On macOS, use the separate manufacturer download and consult the posted compatibility line for your machine.
If the application still fails before a device is connected, record the package version and the startup error. A startup failure and a missing device have different causes, so first establish that the desktop app can open on its own.
Verify the first USB connection
With Gtuner IV open, connect Titan Two through its PROG port with a known data cable. Confirm the device appears before you change firmware or import a preset. When you have an existing project, keep a copy of its source files and record the working firmware and application versions before changing either one.
