OK. I have a Mac, and since I updated to Catalina I can't run BW. So I deleted BW off my hd, because I had a backup iso. This morning I purchased a copy of Parallels. But when I try to install from the iso, Windows wants to reformat the drive it's stored on. What am I doing wrong? Is there a step-by-step procedure for installing BW on a Windows machine from an iso file? Or, if the file is somehow corrupt, can I re-download it? Any help would be appreciated!
