I ran in to the same issue described here- quikeval recognizes the board but is unable to open the DC2039A application (image below on left). I received a link for direct download of the GUI, but don't know where in file structure this needs to be placed for quikeval to find it. If I open the em4015 application directly, I only see a blank gray screen, shown below on the right. Please advise on how I can use the DC2039A application properly.
