These were the DLLs that fixed the 2.05 problem, and I also include the DLLs that are current, and working, with 2.30.
You need to put one in your Windows\System32 and the other in your Windows\Syswow64: the subdirectory structure within the zip file will make it clear which one is which.
Save your old DLLs with an appropriate rename!
One further test is that as I remember it, Pickit 3 worked perfectly with the old MPLAB 8.92, it was just the MPLAB X nonsense that didn't.
The bad DLLs were:
Directory of C:\Windows\System32

Directory of C:\Windows\syswow64
14/01/2014 20:18 199,680 USBAccessLink.dll
