Question

I followed the installation as instructed but driver is not recognized.  During 1st drive installation  an Unregister ASIO error came up.   I reinstalled and the error no longer appears but 192 is not working.

Answer 1

I suggest you try a proper uninstall/reinstall of the drivers. Simply reinstalling them can compound any problems.
