Hello Dan,
Thanks for your tip with Asus. I did not want make my first post too long. Therefore, I did not wrote all the details.
I also download the ASUS C22x_Intel_RAID_VER380110x.zip. In C22x_Intel_RAID_VER380110x folder is the subfolder IRSTe\Install\AsusSetup.exe
Unfortunately we got the same message:
Very strange that the setup would perform a downgrade. Maybe a translation error?
Thank you,
Tom
