Syncfusion.Core.Licensing.LicensedComponent, Syncfusion.Corein the licx file suggests that you may be using the version 18.104.22.168 instead of version 22.214.171.124. With 126.96.36.199, you do not need the version information in the licx file, and it simplifies things not to include it. You only need to include the Syncfusion dlls, not the licx file, in your deployment. Open your project in visual studio, open the refernces node in the Solution Explorer window. Click each syncfusion reference and check its version in teh property window. They should all be the same and what you expect to see. Then click SHow All Files in teh solution explorer and double click the licx file to open it an dcheck its content. Also check its BuildType in its property window to make sure it is Embedded Resource. Then build your probject. The deployment package should only need to be the Syncfusion DLLs listed in teh references and your exe. No Licx. If you are using 188.8.131.52 you might want to download the actual release, 184.108.40.206 and use it.
