 +===== Explanation of Error =====
 +
 +
 +
 +When Control tries to invoke Crystal Reports, it initiates a call to Windows to create an object of type (a.k.a. class) Crystal Report. This message is an error message from Windows telling the user that the class you are trying to create is not registered in the Registry and so it doesn't know how to create it.

 +
 +
 +===== Severity =====
 +
 +**Normal**. User is not down and except for printing all functionality should work fine.
 +
 +
 +
 +===== Possible Root Cause(s) =====
 +  * The Crystal Report XI DLL's are not installed.
 +
 +
 +
 +===== Resolution =====
