Answer 1

Once I faced the same issue on my production server. until the day before everything was working good, but the next day, the error was showing up.

After long hours struggling with issue i remembered for some testing reasons, i had changed the "Application Pool Settings -> Enable 32-Bit Applications" to True, while my server is 64bit; i changed it back to false and everything got normal.

If your server is 32 make this option True, otherwise make it false.

try to add this in your code:

VB.Net

 Imports CrystalDecisions.Shared
 Imports CrystalDecisions.CrystalReports.Engine

C#

using CrystalDecisions.Shared;
using CrystalDecisions.CrystalReports.Engine;

and Add a reference to your project for the required dll, or you can install crystal report viewer to your machine
