Hi,
1) Does the client need to install the Syncfusion?
--------------------------------------------
No, the client does not need to install Syncfusion Essential Studio.
a) Could you please check whether all tools dependent assemblies are available on the client machine?
Syncfusion.Core
Syncfusion.Compression.Base
Syncfusion.Grid.Base
Syncfusion.Grid.Windows
Syncfusion.Shared.Base
Syncfusion.Shared.Windows
Syncfusion.Tools.Windows
Syncfusion.Tools.Base
b) And also, please check if the licenses.licx file embedded as a resource in your project? If not please include license file in your application as an embedded resource. This would embed the syncfusion license into the dll. Now Recompile and deploy the application.
Please refer the following KB article for more details to deploy Windows Forms application in client machine.
