Consequently, if you try to install UserPort on a standard Windows 7 64-bit SP1 system, the system will block it immediately. This is why a simple "download" is not enough; you must also understand how to bypass the security protocols that block the driver from loading.
Using a modified version of the driver that has been "wrapped" or digitally signed.
Manufacturers of legacy hardware (e.g., Advantech, ICP DAS) sometimes bundle a custom-compiled UserPort driver. Check your hardware vendor’s support downloads.
: By design, UserPort creates a "security hole" by bypassing Windows' hardware protection. This can lead to system instability or crashes if a program writes to the wrong port. Where to Download (Legacy/32-bit only)
However, with the advent of the Windows NT kernel (which underpins Windows 2000, XP, Vista, 7, and 10), Microsoft introduced a hardware abstraction layer (HAL). This layer forbids user-mode software from touching hardware ports directly to prevent system crashes and improve stability. Only "Kernel Mode" drivers (signed and approved) are allowed to touch the hardware.
If you can migrate your hardware to USB or PCIe with vendor-provided 64-bit drivers, that is always the safer path. But for those who must keep decades-old industrial equipment running on Windows 7 SP1, UserPort is an indispensable tool.
To use UserPort on Windows 7 64-bit SP1, you generally have two paths:
In the UserPort window, enter the port ranges you need to access (e.g., 0x378-0x37F for the standard LPT1 parallel port).
userport64.sys (should be between 8KB and 20KB). SHA-256 hash for a clean version: available via GitHub release page.
