If the driver is in a ZIP file, extract it to a folder (e.g., C:\Drivers\EZ100PU ).
If your Windows 11 system does not automatically recognize the reader, follow these steps suggested by tech resources like MilitaryCAC and GeniSoftware :
driver from loading because it is considered an "incompatible driver" . : Open Windows Security from the Start menu. Go to Device security > Core isolation details . Toggle Memory integrity to Off .
If Windows 11 refuses to accept the driver, try disabling "Driver Signature Enforcement" in Windows Recovery Environment (Advanced Startup), though for the EZ100PU, simply pointing Device Manager to the driver folder usually works without this step.
