Crystal Report Viewer Control error

Please Help, I have a web application developed in .net 2005 which is using crystal reports developer product version 10.0.0.533.

This web application with crystal is working fine on my local machine with OS windows xp, but on the windows server 2003 the application web form is running into "couldnot load file or assembly 'CrystalDecision.VSDesigner, Version=10.0.0.3300' or one of its dependencies"

I have compared the assembly information of my local machine with that of the server and could not see the crystaldecision.vsdesigner version 10.0.0.3300 on the server 2003. I have uninstalled microsoft .net 2005 and crystal reports and installed crystal first and visual studio .net 2005 next and vice versa but still could not see that particular assembly available in the windows 2003 server.

Please suggest as what to do for the assembly to be available on the server so crystal report viewer control can be created with out error. Thanks for any help.
