[issue25089] Can't run Python Launcher on Windows

Steve Dower added the comment: I've added a brief doc section on modifying and removing the install, so hopefully that suffices for this issue. If the original issue occurs again, feel free to reopen, but I think it'll be okay. I have a few ideas about changing the installer to be more intuiti

[issue25089] Can't run Python Launcher on Windows

Steve Dower added the comment: The convention when modifying installations is to specify the end-state that you're want, so unchecking something indicates that you want to remove it. This could be made clearer, but it's probably a significant redesign of the UI. At the least we could specify i

Mark Lawrence added the comment: Using "modify" rather than "repair" fixed the launcher issue, a pity about this. py Python 3.5.1 (v3.5.1:37a07cee5969, Dec 6 2015, 01:54:25) [MSC v.1900 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import t

[issue25089] Can't run Python Launcher on Windows

Steve Dower added the comment: There's a separate issue in the 3.5.1 installer where the launcher is always deselected on upgrade. I'm currently working on a fix to force it to always install and we might push out a new 3.5.1 build later today. If you go through Modify rather than Repair then

Mark Lawrence added the comment: After running the 3.5.1 64 bit web installer the py launcher has again been lost, i.e. "'py' is not recognized as an internal or external command, operable program or batch file." Running the web installer in "repair" mode hasn't made any difference. I've att

Steve Dower added the comment: Hopefully with the extra logging we'll be able to see if something is failing at the point of detection. Any failure here (permissions in registry, etc.) will cause the launcher to not be installed on upgrade (which might be the same as removing it... I need to s

Steve Dower added the comment: Yep, as part of the upgrade detection we're choosing not to install the launcher. Not sure whether that's because of a bug or a previous install on your machine, but I'll take a closer look. -- assignee: -> steve.dower __

Steve Dower added the comment: Just the main log file from the initial install is enough if there's no log for the launcher. It probably means the initial setup startup deselected it for some reason. -- ___ Python tracker

[issue25089] Can't run Python Launcher on Windows

Steve Dower added the comment: Yeah, it's basically impossible to manage PATH automatically. You've probably installed 3.5 just for yourself while 3.4 is installed for all users. In this case, 3.5 will always lose because Windows puts user paths after system paths. You could modify 3.4 to remo

Terry J. Reedy added the comment: For anyone else reading this, Mark says he already re-tried with 3.5.0. The only problem I had with the install on my Win7, with 2.7.10, 3.4.3, and 3.5.0rc3 already present, is that 3.4.3 is still the default python (started by 'python') in spite of checking e

Steve Dower added the comment: I don't understand what you did and what the result was from that thread. * What options did you select when installing 3.5? * What other Python versions did you have? What options were used to install them? * Where was py.exe before installing 3.5? * Can you atta

New submission from Mark Lawrence: I first asked a few days ago, see this thread http://www.gossamer-threads.com/lists/python/python/1216917. You can work around it by running "repair" but it takes an age to run for what, to me anyway, is a minor irritant. -- components: Windows mess
