Hi Andrea,
Thanks for contacting Syncfusion support
Syncfusion had removed Classic products(ASP.NET and ASP.NET MVC), Silverlight, and LightSwitch Silverlight platforms from the Syncfusion Enterprise edition setup and providing them as individual platform setup from the 2015 Vol 4 release(v13.4.0.53).
Hence, you can download and install the required Syncfusion ASP.NET Classic setup latest version from the following download link:
Please refer the below documentation link:
Let us know if you have any further queries.
Regards,
Prince
