I currently have both shortcuts on my desktop, but I prefer to open files by double clicking in Explorer rather than opening the programme then finding and opening the file.
This obviously saves massive amounts of time, grin but it's what I'm familiar with.

As far as I can see, render settings are the same for 32 bit and 64 bit versions and these are both as I had set in BIAB2018, so I don't want to change 64 and possibly mess up 32.

Thanks to both for the replies, as I have previously said I can live without 64 bit for the moment, and just accept this as the regular annual dance around issues that seem to accompany each update
