Hi,

I´m trying to generate an automated install and uninstall from Python.

For this I normally use cmdlines, but I got some issues.

If I try to uninstall by my automated version I got the problem that it doesn´t finish.
When I do this at the PC himself it works fine with PathToPython.exe /uninstall but i have to "click" close at the end of the setup by myself.
So I think my problem with the automated version is that it doesn´t "click" close, because the uninstall itself seems to work fine.

Are there some more parameters I could give?

Another Issue is the PythonLauncher. Is there an cmdline by himself to uninstall?

Pass /passive to have it automatically close at the end, or /quiet to avoid popping up a window at all.

Can you clarify what you mean by launcher? There are a couple different things you could be talking about and I don't want to give you the wrong answer.

Hi Steve,

Thank you for your response.

Does the /quiet and /passiv works together with the /uninstall?

When I read the Documentation it seems that the /uninstall included the /quiet.
Could you tell me what exactly is the meaning of the /passiv?

So am I right that the cmdline: "PathToPython.exe /uninstall /quiet" should work?

I´m talking about "Python Launcher for Windows"
https://www.python.org/dev/peps/pep-0397/
It appears in the System Control after installing Python3.7.3

ciao

ok the "PathToPython.exe /uninstall /quiet" seems to work.
Thanks for this hint.

I found the Python Launcher in the registry path for x86, this was not what I expected after install Python3.7.3 x64.

In the registry they show an uninstall command what works when I use it direct on the PC.
MsiExec.exe /X{A28C27E4-A725-482A-9C65-61EDC0E4D583}

But it won´t work as an automated install command over network. Probably not the fault of Python Launcher.
Maybe there is an other opportunity to uninstall PythonLauncher?

ciao

Ok I´m done.

Thank you very much for your quick advice.

The documentaion is kind of misleading.
"The /uninstall option may be passed to immediately begin removing Python - no prompt will be displayed."
Because of the last part I thought the /quiet is included and not necessary for the uninstall.
After I found the registry entry from "Python Launcher" I get the uninstall cmd.

Maybe you could still tell me something more about the /passiv?


That is what works for me.

Uninstall Python3.7.3:
PathToPython.exe /uninstall /quiet

Uninstall Pythonlauncher:
MsiExec.exe /X{A28C27E4-A725-482A-9C65-61EDC0E4D583} /qn

ciao

Sorry for the slow reply.

> immediately begin removing Python - no prompt will be displayed

This is meant to imply that no *confirmation* prompt will be displayed before uninstall starts. Documentation patches are welcome :)

> tell me something about passive

The /passive option means the user can see progress and (if appropriate), cancel the operation, but otherwise does not have to interact with it at all. This is good for semi-interactive scripts, where the user starts it and wants to see what's happening, but could also walk away and let it run to completion. With /quiet, there'd be no progress or errors (generally /passive will stop and wait if an error occurs), and without either the success page would also stop and wait.

These are fairly typical command line options for installers on Windows, and the Python installer users them in the standard way. Mostly because we haven't done anything to customize them from the installer toolkit we use :)

This is referring to Doc/using/windows.rst
