Can you please elaborate? I don't quite understand the relationship
between the UI sequence and the execute sequence:
- Is it true that, with full UI, it first executes the entire UI
sequence, and then the full execute sequence? Then why do people
typically duplicate actions in both sequences?
- If not: what parts of the execute sequence are executed under
I'm somewhat worried that the action would be executed even after
the user was already queried for the targetdir (although the
condition should avoid TARGETDIR being reset).
Also, I currently install by default into [WindowsVolume]PythonXY.
Would it be better to install into [ROOTDIR]PythonXY, as this would
be the drive with most space?
