HP Envy 7640 drivers corrupt, cannot uninstall

[KJ-san]

Hello,

    Once again Win10 updates have crashed my networked 7640 printer, and now nothing I do works.

HP Smart CAN see the printer, ink levels, and everything, however WINDOWS CAN'T see it.

I tried to install the latest "Full_Webpack-40.15.1230-EN7640_Full_Webpack.exe" and I quickly regret my decision!!!

 It has COMPLETELY corrupted my system.  It's messed my computer up so bad that I CAN'T INSTALL IT.  

I've tried deleting the files on my Hard Drive, running the "Uninstall.......msi" script from the regedit.exe, but NOTHING works.

I managed to get it to connect via USB cord using the original install disk, but when I tried to connect to the printer through my network, I lost everything again. 

When I tried going back to the "original" CD that came with the printer, it runs for about 1 minute and says "Installation Complete" but does NOT install anything.

The latest software is worse than a virus.....  I'm taking college classes and not being able to print or upload my work is really hurting me.  

My wife has the same HP Envy 360 laptop as me, and yet her laptop NEVER has these issues.  Yesterday I had to email her my Lab assignment so she could print it for me.

[ UPDATE 1/23/2023:  I managed to repair the install enough so I can scan/print through the USB cord, but oddly, Win10's "Devices and Printers" ONLY sees the Fax part of the machine.  At least I'm operational for now... The other problems (wireless network printing and trying to remove the crashed installer program) are still there. ]

HOW DO I....

 A)  Get this "Full_Webpack-40.15.1230-EN7640_Full_Webpack.exe" garbage COMPLETELY off of my machine, and 

 B)  How do I reinstall my printer drivers so I can connect to a NETWORK printer again.

 C)  Prevent MS Win10 updates from trashing my drivers every few months?  This is the 5th time this has happened, and it's getting progressively worse/harder to repair every time.

Thank you
