Assembly binding logging is turned off?

Very recently I faced an issue with a web application which is hosted on the Windows 2003 server. While browsing the web application from IIS the following message is giving.

Error:
WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].


Reason:
The error is saying that there is a dll file missed which is useful for the Crystal Decisions.

Solution:
To resolve this issue I installed Report Viewer which is a redist package. The problem is solved. :)

Happy Coding...
