Service Terminal (ST03A) V3.9 and V3.8
For V3.8.01 a different license key is needed, but all version revisions of V3.9 use a common (the same) license key for activating.
If you have already activated an older (i.e. V3.9.00) revision of V3.9 to activate a newer one (i.e. V3.9.02) please
- uninstall the older revision of V3.9 without checking the "Revoke license key" option during the uninstallation to keep the license key activated on this PC intact,
- download and install a newer revision of V3.9 on the same PC,
- start it and check the activated license under Tools / Licensing / Response...: the key activated with the previous V3.9 revision will be accepted automatically.
