Hi Branden. I'm Greg, 10 years awarded Windows MVP, specializing in Installation, Performance, Troubleshooting and Activation, here to help you.
MSXML 4.0 is no longer supported by Microsoft so it would be at your own risk. See: https://github.com/MicrosoftDocs/sql-docs/issue...
You can ask more about your usage in Github forum (above) as it's more suitable for the issue than a general end-consumer forums.
Download available here:

Set a System Restore point first so you can go back if necessary: https://www.windowscentral.com/how-use-system-r...
Feel free to ask back any questions. Please report back results for all steps given so I know what else to suggest if necessary.
