WANTED Gira Control 9 KNX recovery USB Stick

I'm looking for a Gira Control 9 USB recovery stick. This allows me to reinstall the default KNX app. I believe the Control 9 Client 1 and the Control 9 KNX 2079 00 use the same recovery stick. First generation. I'm stuck, so I use my two Control 9 to control my Gira Alarmzentrale 1142 00. My Control 9 currently boots into Windows, as it was used with a home server previously, and the KNX app has been deleted. In the KNX version, the KNX app should open automatically after windows boots. I will just use it to arm/ disarm & acknowledge telegrams via group addresses. To do this I need the Control 9 KNX app. Hopefully the recovery stick will reinstall this for me. Tips are also welcome :-) They came for free in the box with every Control 9, I believe, so someone surely has one lieing around 🙏 NB: I will NOT be using this with a Home Server.
