The key checkpoint: For Could not link, the recorded recovery puts the launcher on the same drive as the game. For Illegal byte sequence, it uses a short plain launcher path, then rechecks the game paths and runs Set up.

Before you start

  • Keep the recorded RyGT7 build and your firmware version available.
  • Use your own supported module and firmware files.
  • Retest the same launch stage after one correction.

Walkthrough 01

Could not link: move the complete launcher folder

Video reference 0:00 ↗

Close RyGT7. In the recorded recovery, the creator puts the entire launcher folder on the same drive as the extracted game, then opens RyGT7 from that copy. Keep the application’s support files together. Moving only the executable does not reproduce the shown route. Check which copy you launched so you do not accidentally reopen the old shortcut.

Walkthrough 02

Illegal byte sequence: use a short plain launcher path

Video reference 0:19 ↗

The successful attempt uses a short, plain path for the launcher close to the drive root, outside the previous nested folders. The game stays in its existing location. This is the path change shown in this recording, rather than a claim that every error with the same text has one cause. Keep a copy of the previous arrangement until the new launch works.

Walkthrough 03

Recheck the game page and run setup again

Video reference 0:42 ↗

Open the gear, choose Game and inspect the selected paths after moving the launcher. Press Set up and wait for the status Ready. Press Play. Then return to the launch screen and start the game. If a different message appears, preserve the full text and the run log before changing more settings. The full installation reference is collected in the resources above.
