Hi Vaishali,

Thank you for your interest in Syncfusion products.

Normally this error occurs while you missing the compression dll. Please include "Syncfusion.Compression.Base.dll" assembly in the bin folder.

If you only need to deploy grid application, then there is no need for Syncfusion.Compression.base.dll. You are converting Grid to Excel, so you need to deploy both XlsIo.base and also it''s dependent dll “Compression.base” while deploying the application.

Please try this and if the problem still exists could you please try to send your sample so that we could sort out the cause of the issue and provide you a solution?

Regards,
G.Yavana

Hi Mehmet,

Sorry for the delay in responding.

Please downloading our latest version from the below forum thread and refer the below steps:

http://www.syncfusion.com/support/forums/message.aspx?MessageID=75132

1.Run Assembly Manager(Syncfusion->Essential Studio 6.3.0.30->Dashboard) and remove all other versions.
2.Now Install the version 6.3.0.30.
3.Please verify the assemblies are in the following folder C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PublicAssemblies
6)Then recompile your application

The "Syncfusion.Compression.base.dll" should be placed in the public Assemblies folder. Please check and if the assembly could not be found, try to create a direct trac incident regarding this issue so that we will provide you a solution?

Regards,
G.Yavana

I know this is an old thread, but I ran into this error recently on a deployed server. What we eventually found was that the XlsIO was looking for the MVC 1.0 DLL, but the server that I deployed it to had never had 1.0 installed.

Thought I would share the information in case other run into the same issue.
