Crystal Reports PDF Export Not Working


If the error is Object reference not set to the instance of an object, then possible reasons are:

a) File Name (Report) incorrect.

b) Stored Procedure Missing.

c) Fonts (Arial , Times New Roman ) changed due to Windows Update KB3102429.


In such a case copy these fonts from Old System  C-> Windows -> Fonts to current system Fonts folder. Restart the system and reports start working.
