hi Carl,
I did downlaod and install MQX4.1 yesterday from here:
MQX: Freescale MQX™ Software Solutions
i didn't install any patch for it yet. but all the pdf file in my MQX4.1 install folder can work.
i suggest you check:
1. if your MQX4.1 install folder is ok. Please try to download MQX4.1 from above link
2. if the problem is due to your computer infect virus. please try to install the MQX4.1 to another computer to see how it works.
Hope this helps!
