Is there a reason that a XY64 instance needs to be closed to update XY32, even though I set them up with separate data folders?

Do you mean because the installer says so? No, that's not necessary. I'll change the wording.

Even with only XY64 active when updating XY32 it shows the usual message to close all XY instances before proceeding.
I have to admit though, I never tested whether it causes any further problems if I just ignore the message.

Edit: Ok, just tested this with the latest XY32 update (1006) while XY64 was still active and it worked
Plus the re-worded message stating to close 32bit instances helps to avoid future confusion.
