Symbols are not loaded in WPA


  • Hello,

    For some reason WPA would not load symbols anymore for me. It worked before but it stopped working for some reason. Below is output of diagnostics console. Clicking on Load Symbols do not produce any output whatsover. How do I troubleshoot this? 

    InitializeSession: OnBegin: Starting pass 2
    InitializeSession: OnEnd: Finished pass 2
    InitializeSession: OnScheduleEnd: hr=0x0
    DBGHELP: Set Options: 0x80001602
    DBGHELP: Symbol Search Path: srv*d:\symbols*;

  • WPA doesn't ship with the symbol loading DLLs so it is very easy to get no symbols or incredibly slow symbol decoding. You can solve both of these problems by copying known-good symbol DLLs into the WPA install directory.
