The update is not applicable on your computer.
I was near certain my computer was the correct type... Maybe I overlooked something?
I did install both of the USBTinyISP drivers, but it always gives the same errors... Again, my issue was exactly the same in every way
Were there any specific steps you took to install the hotfix?
Also I'm sorry if this thread is closed, but it's the only one that I found that was exactly the same as mine!
