All drivers EXEPT the one for my controller installed...?!

Hi, I just bought a DDJ-RX and I get this well known error when trying to select ASIO. I followed all procedures (https://forums.pioneerdj.com/hc/en-us/articles/212041406-What-should-I-do-when-an-error-appears-after-opening-DDJ-XDJ-audio-driver-) without any success.

Windows 10 (Version 1703) keeps using some Standard Drivers instead of the Asio Drivers. When I try to Change the Drivers from the Control Panel manually I was surprised to find no sub-Folder for my Hardware under pioneer/rekordbox/Drivers.

I have to say that I'm pretty disappointed with the Software Quality. It was impossible on my Windows 10 Computer to update the Firmware - even with the jar runner Workaround. On my Windows 7 Computer it took 4 attempts to update the Firmware. After the second attempt with an error message I thought the process broke my Hardware because it was not reacting anymore. it is now running 1.04 - but that didn't Change my asio Problem...
