Hi John,
That kernel32.dll is not part of OP Config, but is something to do with Windows 7, and so far as Google has been able to enlighten me, indicates that Windows doesn't think that OP Config is compatible with Windows 7. About a year ago there was a major update of OP Config that maybe was the cause of this, since it certainly did previously work with Windows 7.
Maybe it's possible to get it to work on Windows 7, but since I no longer have that operating system I'm unable to troubleshoot it. What you can try instead is to use an older version of OP Config (and TCB firmware).
You'll want to uninstall the OP Config you put on there, and then download version 0.93.78 (dated 11/3/2024) from the
OP Config prior releases page. This was the last version before the major update so I'm assuming it would still be compatible with Windows 7, but I can't be sure.
Install that on your computer and see if it can run ok. If so, then you will also need to flash the corresponding old firmware onto your TCB. You want 0.93.78 again (the TCB firmware is dated 3/6/2024, and
you can download it here. You'll have to right-click on the 0.93.78 link and select "Save link as" to save the hex file to your computer (otherwise it will just show you the hex in your browser).
In OP Config, go to the Firmware tab, and rather than clicking the "Get Latest Release" button, click the "Use your own Hex" button instead, and then select the 0.93.78 hex file you downloaded, then flash that to your TCB.
Hopefully that works, let me know.
