[Octave-bug-tracker] [bug #51632] MS Windows portable (i.e. zip) version cannot find pre-installed packages, needs pkg rebuild, not mentioned at first run

[Nicholas Jankowski]

Follow-up Comment #27, bug #51632 (project octave):

Yes, Portable is a separate issue and I guess we are getting sidetracked. 
Doug's comment #26 describes a Portable distribution as it's usually intended.
Octave is close to being so, but yes, currently Mike's comment #25 description
of the zip usage is probably more correct. 

What options are there for a 'run once' set of commands that would re-run
after a 'reinstall' or 'upgrade' of the zip package? There is a 

C:\Octave\octave-4.2.1\share\octave\site\m\once_only

folder.  What are the checks/conditions to execute things in that folder? 

I know that on a new machine I get the 'this is your first time running
Octave' dialogue since (i assume) it doesn't see anything in my User folder,
but it only ever happens once on the machine. If I delete Octave and restore
from the zip, or put a new version on, it doesn't create that dialogue again.
