When I open Windows Performance Analyzer I am told to open the .etl file, which it does. I then am told to select File > Configure Symbols. Which does not exit. The load symbols and configure symbols paths from the Trace menu are grayed out ****lets out big sigh**** I tried the suggestions from here Xperf and WPA symbol problem link However all to no avail. Help!!!
