[issue45073] windows installer quiet installation targetdir escapes "quote"-symbol

[DMI-1407]

New submission from DMI-1407 :

If the windows installer (Python 3.8.9 64bit exe) is run in quiet mode and the 
TargetDir option is used, then the last quote (") symbol gets escaped if the 
path ends with an backslash (\).

Example: /quiet TargetDir="D:\pyt hon\" AssociateFiles=0
Result: TargetDir=hon\" AssociateFiles=0
this raises the error that the path contains a invalid character... (the quote 
ofc)

Example: /quiet TargetDir="D:\pyt hon" AssociateFiles=0
Result: installs correctly


so in general "D:\pyt hon" indicates a file thats named "pyt hon" where "D:\pyt 
hon\" indicates a folder.
whatever "D:\pyt hon\" should be valid and i dont understand why the first 
backslash does not escape the p and leads to "D:pyt hon" ...

its really annoying, pls do at least write a notice into the docs that the 
installer behaves like this. :/

[issue32592] Drop support of Windows Vista and 7 in Python 3.9

[DMI-1407]

DMI-1407  added the comment:

Is a Windows Version dropped on "normal" end of life or when the extended 
support ends?
Windows 7 extended support ends in 2023 (april i think).

As far as i understood it, Windows 7 gets unsupported from Python 3.9 because 
of code removal?
So wouldnt it be better to keep the code until the extended support of Windows 
7 ends?
