My ML won't be here till tomorrow. I told Windows 10 (64 bit) to install SXi-Q using the Setup .exe in compatibility mode. It was installed.
Running SXi-Q I clicked on update, clicked on Open File, opened ML_Class_V2203_20160114_SX Pure-English.SXI. On the SXi software it now says File Opened: ML_Class_V2203_20160114_SX Pure-English. Clicked on Upgrade. It says File Opened: ML_Class_V2203_20160114_SX Pure-English.SXI Please Connect to Device before Upgrading!
So this should work without needing to jumps thru the hoops previously posted, right?
