Problem with DiabloIV installation using LUTrIS on Steam DECK

I am following the instructions , get to BN logon can log on, even downloaded DIV but LUTRIS install never finishes?! Running installer opens WINE browser. How do I execute your installation script directly on my DECK?
I have done this MULTIPLE TIMES and have not got it to complete correctly yet?
I have added LUTRIS to my STEAM instance already, did this mess it up?
Really want to get this installed on my DECK!!!
