Python for Windows (python-3.7.4.exe) location confusing
by Jim J. Jewett Sept. 12, 2019

Sept. 12, 2019

Is it possible for the installer to check whether or not there is a pre-existing system-wide launcher, and only do the complicated stuff if it is actually there? -jJ

Python for Windows (python-3.7.4.exe) location confusing
by Armen Michaeli Sept. 10, 2019

Sept. 10, 2019

Hi all, The installer dialog mentions Python will be installed in something like $USERPROFILE\AppData\Local\Programs\Python\Python37-32 while at the same time suggesting it will be made available for all users through the "Install launcher for all users (recommended)". This is confusing -- if the package is to be made available for everybody, it shouldn't be installed somewhere under the profile folder of whomever is installing it, normally other people can't even access this folder at all. It should be installed in %Program Files(x86)%, unless it is a private installation indeed (the "Install launcher for all users" is unchecked). Is this an omission of sorts? Is one expected to correct this themselves, during installation -- I don't see where one would even specify the installation folder? [image: image.png]
