Windows 7 USB Serial Driver

My Windows 10 system correctly recognizes my Teensy 4.1 configured with a USB Serial Port; it assigns Windows driver usbser.sys to the device.

When plugged into a Windows 7 system, however, the Device Manager recognizes that a USB Serial device is attached but complains that no driver is installed for this device. Asking the Device Manager to find the driver proves to be unsuccessful...

How does one load the correct driver onto Windows 7 to talk to the Teensy USB Serial Port?

Thank you very much for help with this problem,

Thanks so much for the prompt reply, Paul! I had not noticed that link on the Downloads page; this is exactly what I need to send to my Consulting client.

From your '27,009 Posts' I see I'm not the first newbie that you've helped....;)

P.S. These Teensy CPUs are fantastic - I recently had to design-out a Raspberry Pi (made of Unobtanium) and design in the Teensy 4.1...
 
After I put MicroPython onto my Teensy 4.1 I had the same problem on Windows 7.
using the "Windows Serial Installer" did not solve it.

I ended up using Zadig: https://zadig.akeo.ie/
