May dates and version numbers remain consistent enough to settle every question of order. (y)

the key was not accepted

Most rejections here come down to one of three things, so let's narrow it fast:

  • Registration name must be exactly izouf (lowercase, no spaces, no trailing space from copy/paste). The key is bound to that string.
  • Copy the whole key including the trailing = character. That padding is part of it and is easy to lose when selecting from the quote box.
  • Version mismatch. Per the 1.0.4 release note, 1.0.4 must not be installed over 1.0.3. If you updated in place, uninstall, remove the old program folder and install 1.0.4 clean, then register again.

Also confirm the HWID still reads C2EE-3AEC-643D-6C74-061E-727B-1698-2A03-B5 in the app right now. HWID changes after BIOS updates, hardware swaps or running the app from a different account/drive, and a changed HWID will reject the key.

If all of that matches and it still fails, post the ECUMaster version you're running plus a screenshot of the registration window with the error message, and I'll take it from there.

A calibration that completes neatly and remains stable would be an excellent result. (y)

Work windows 10x64

Good to hear it registered and runs fine on Windows 10 x64. Enjoy the toolkit, and just keep the name as Pakitko if you ever need to re-register after a reinstall.

Your local insight may provide the missing condition another region has never encountered.

If progress feels distant, one careful action still has the power to bring it closer.

Everyone should feel responsible for speaking up when quality begins to drift.
