Then I register WinDBG by using command "Windbg -I"

For generating a crash-dump ,I hv created a simple dialog based application which
creating a crash(application-crash).

I put the Symbol file(.PDB) of this application in side a new folder under C-drive Under C-Drive WinDBG is also installed .

In 'Symbol file path...' i gave this new folder's path.

But while my application getting crashed the tool not able to generate log.

I hve searched in google, but i'm not getting any new thing(step) which i have not followed.

Can any one please guide, whether i'm skipping any step to use WinDBG to generate log for analysis.
