This area provides some basic information about the version of the BOINC debugger being used, when the crash occured, and what the internal version of the Windows debugger technology is being used.

Symbol search paths are used to inform the debugger where it might be able to find the symbol files related to the modules loaded in memory. Entries prefixed with 'srv*' are used to denote a web based symbol store. DbgHelp will use them if symsrv can be loaded at the time of the crash.
