Older JAF drivers (pre-2012) were written for 32-bit systems. Microsoft’s adoption of 64-bit processors introduced Driver Signature Enforcement (DSE) and Kernel Patch Protection (KPP). Many JAF drivers used unsigned kernel-mode components to communicate with the USB dongle.
On a 64-bit system, Windows blocks unsigned drivers by default. Therefore, a working jaf pkey driver 64 bit must either be digitally signed or installed with special permissions (like disabling driver signature enforcement). You need the “JAF P-Key 64-bit Test Driver”

The JAF P-Key is a hardware security dongle utilized by the JAF software suite, primarily used for flashing and servicing Nokia mobile devices. This report outlines the challenges of using the JAF P-Key driver on 64-bit operating systems (Windows 7, 8, 10, and 11). The findings indicate that official driver support for 64-bit architectures is obsolete, leading to significant installation difficulties, driver signature enforcement conflicts, and security vulnerabilities. Where to find
The original JAF P-Key drivers do not natively support 64-bit architecture. While "cracked" or modified third-party drivers exist, they are not digitally signed by a trusted Certificate Authority. Microsoft Windows (specifically Vista, 7, 8, 10, and 11) requires kernel-mode drivers to be digitally signed. Without a valid signature, the operating system blocks the driver installation.
The primary reason the old JAF PKey drivers fail on modern 64-bit Windows is "Driver Signature Enforcement." For security reasons, modern 64-bit versions of Windows require all kernel-mode drivers to be digitally signed by a trusted publisher. The drivers for the JAF box and PKey dongle were created years before these strict requirements were enforced.
As a result, when you plug in the box, Windows often ignores the driver or throws a "Code 52" error, stating it cannot verify the digital signature.
