Hello I am unable to download Python’s version of 3.9.2(64-bit) on Windows 10 Laptop
When I install packages its shows error 0*80070643
Google the error code with proper spelling, 0x80070643 gives a few result, did you try any of them? This is a generic install error that is more caused by your system than by python.
As @MegaIng says a web search will give you lots of help.
Try a search for “python 0x80070643” to find how other people have fixed this Windows issue.
Also why are you install such an old version of python?
3.12 is the latest version and some people need 3.11 when specific packages have not been released for 3.12 yet but otherwise 3.12 is recommended.
