RE: Python Install Woes
#1
I am trying to install Python 3.7.3 via the install file available here: https://www.python.org/downloads/.

Upon running the application and following the prompts the installer runs for awhile, then the progress bar starts to move backwords, and then ultimately it stops and tells the user that installation has failed. error code 0x80070643

I have done my best to remove any traces of an old installation from my PC. Any advice on how to work around this?

does not sound good, and seriously doubt there is an issue if installation file came from python.org:
please advise which OS, and as much computer information as you can provide.

Also look through: https://python-forum.io/Forum-Python-Ins...-Execution

and perhaps try the installation recommendations for your system

While installing Python 3.7.3, and getting an error code 0x80070643
means that another installation is also going on. Check for the
windows update and doing the update, reboot your system and then try
for installing Python 3.7.3
