my os is win7 64 bit. I previously installed smart snippets 3.6 which can work properly, I have downloaded file into flash by version 3.6, but after I installed 3.9 version, it didn't work, when I click "connect" (for downloading to flash), it reports below:
failed downloading firmware file to the board
I have uninstalled the 3.9 and reinstalled 3.6 back and forth for times, I can not make it work now.
how to solve it?
