I wonder if it has to do with USB drivers. We had to go through some monkey motion to get USB drivers installed. It's documented at http://ftp.uslinc.com/ftp/Products/JSD-100/Documents/Technical/Windows%208%= 20USB%20Driver%20Installation.pdf .. If it were a driver issue, though, I'd expect MPLAB to not see the ICD2 at all. I'm still running MPLAB 8.92 under Winows 7. It continues to work well. I've tried migrating projects to MPLAB X without success.
