I am now able to run by VBA code. Thanks very much.
By the way, the update dialog produces the warning that I need to quit all copies of SAM before preceding. Closing SAM and clicking Okay just redisplayed the dialog. I repeated the process, quitting SAM before I clicked Update on the SAM update executable's dialog, Same result. I looked at task manager and identified the update .exe but, before running it, it occurred to me to just rerun the SAM install from the new rev2 package, as suggested in the updater's dialog. That worked, so I'm good. Might be a stumble for others.
