Hi, Gang.
When I asked for the One Step Update today, it offered to update me from Release 3 to Release 4. Of course I said yes. It churned for a while, then announced that Release 4 was NOT installed. After a couple more trips on the merry-go-round, I opened an Administrator:Command Prompt window and ran qw.exe. Release 4 was offered; I accepted; it installed cleanly in less than a minute; all done! ;
