You're welcome!

Just a quick tip for the installation: make sure to disable your antivirus or Windows Defender before extracting the archive. The loader is often flagged as a false positive and will be deleted instantly if real-time protection is active.

Also, always run the loader as Administrator to ensure it can communicate properly with the interface.

Enjoy!

One last important detail regarding the ATMEGA162 version:

Make sure to block the application in your firewall or disconnect the internet while using it. If the software tries to update the interface firmware from the official server, it will likely "brick" the cable (desynchronize the liсеnsе) and you'll have to reflash the EEPROM to fix it.

Let us know if you run into any connection issues!

No problem!

If you plug the cable in and Windows doesn't recognize it immediately, check Device Manager. It should appear under Universal sеriаl Bus controllers as Ross-Tech Direct USB Interface (or similar).

If it shows up as "USB sеriаl Port" or has a yellow triangle, you might need to manually update the driver by pointing Windows to the VCDS installation folder.

Good luck with the diagnostics!
