Thanks Radioman and everyone else here who have contributed to this forum.
I just got the MiniPro TL866CS off Amazon, and it looks good so far. It works fine on my desktop pc running Windows 7
The only issue I have is probably "DotNet" related, but I am not sure. Other software (Autodesk, and some others) have the same error caused by the type of installation inf file used or the setup file itself.
I can't install the USB driver on either of my 2 WinXP laptops. The programmer software installs, it thinks it installed the USB driver, but after I connect the TL866CS to the cable when instructed to, the "Found New Hardware Wizard" retrieves the device name (MiniPro TL-866 Programmer" then "MiniProWdf".
After a while of the red light staying solid and yellow flashing, the wdfcoinstaller runs from the .inf file and I get an error from the "Found New Hardware Wizard" window saying something about "no signature found". Screenshot attached:
Anyone else have this problem? Any solutions? Thanks.
