Thanks for sharing the link.

Regarding the issues on Windows 10 x64, these older KTag utilities are notoriously finicky on newer OS builds. They were mostly written for XP/Win7 environments.

Here is a checklist to get it running:

• Antivirus / Windows Defender: This is the #1 cause. Defender often silently blocks or quarantines the executable immediately upon extraction. Create a folder, add that folder to Defender's "Exclusions" list, and then extract the file there.
• Run as Administrator: Right-click the exe and select "Run as Administrator". This is mandatory for tools that need to access USB ports or write to SD cards directly.
• Compatibility Mode: Right-click -> Properties -> Compatibility -> Set to Windows 7 or Windows XP (Service Pack 3).
• Visual C++ Runtimes: Even though your OS is x64, this utility is almost certainly 32-bit. Make sure you have the Visual C++ Redistributable x86 packages installed (specifically 2008, 2010, and 2012 versions).

What exactly happens when you double-click it? Does it give a "Missing DLL" error, or does the window just flash and disappear?

If it's an SD card repair tool, sometimes it won't launch unless it detects a card reader with a specifically formatted card (FAT32) inserted.

no, it loads up ok but when i load a backup file, sometimes eeface error and sometimes device not connected although ktag clone 5017 is connected and working properly, i'll try your solution and i'll also give it a shot on 32bit system, i'll post the results, cheers bin.

If you are getting "device not connected" while the unit is actually plugged in, it is almost always a driver conflict or an exclusive access issue.

A few things to check before you wipe your system for a 32-bit install:

• Close KSuite/K-Info: Make sure no other software that talks to the KTag is running in the background. The driver can only handle one active connection at a time.
• Driver Version: Windows 10 automatically installs the latest FTDI drivers, which often break compatibility with these older utilities. Check your Device Manager. If you see it listed as a generic USB sеriаl device or if the driver date is very recent, you might need to manually force the older driver (version 2.12.00 or older) usually found in the KSuite Driver folder.
• USB Port Power: Try a USB 2.0 port if you have one. USB 3.0/3.1 ports on newer laptops sometimes handle the handshake too fast for these older NXP chipsets during the "utility" mode operations.

The eeface error is often related to the GUI skinning library used in these tools crashing on 64-bit memory addressing.

Testing on a native Win7 x86 (32-bit) is definitely the best move. These utilities were designed in the XP/Win7 era and often hard-code memory addresses that don't exist in the 64-bit space.

Let us know how the 32-bit test goes. If it still fails there, we might need to look at the SD card inside the unit itself—sometimes simply taking it out, formatting it to FAT32 (slow format) in a card reader, and putting it back in helps the utility see the device.

i'm away tomorrow, i'll follow your advice and report back on friday, sure would be a handy tool if it works with clone tools, cheers bin.

Safe travels. Just a quick heads up before you try it on Friday:

Since you mentioned you are using a 5.017 clone, be very careful with these utilities. Most of the "KTag Repair/Utility" tools circulating (like v2.0, v1.9, etc.) were originally designed for the older FW 6.070 / 7.003 units to reset tokens or fix the NXP checksums.

The 5.017 hardware usually runs a different SD card structure and is "unlimited" by design (doesn't use the standard token countdown in the same way). If that utility writes older protocol files (meant for 6.070) onto your 5.017 SD card, it will likely stop working with your current KSuite version (2.23/2.47/2.53).

Crucial step:
Before you let the software write anything to the unit, take the SD card out of your KTag, put it in a card reader, and make a full raw image backup (using Win32DiskImager or similar).

That way, if the utility "fixes" it by downgrading the files and bricks the tool, you can just flash your original image back to the card and be back up and running.

Let us know how you get on.

gotcha gemini, i was calling you bin , goodluck.

Haha, no worries! In this business, being called "bin" is pretty standard—we spend half our lives staring at bin files and hex dumps anyway.

Fingers crossed for the Friday test. Just don't skip that SD card backup step. It's the only parachute you have if the utility decides to overwrite the wrong sectors on that 5.017.

Catch you then.
