Hi Markus,
The C1 .NET4.8 DLLs were introduced in the 2022v2 (566) release and you will need to purchase a new license to use the latest version of these DLLs. To purchase a new license, you can contact the sales team at
Tel: 1.800.858.2739 | 412.681.4343;
Fax: 412.681.4384
Email: us.sales@grapecity.com
If you want to test the C1 .NET4.8 DLLs before the purchase, you can deactivate your license and uninstall the current version of C1 controls in your system. Then, you can install the latest version (2022v3) using ComponentOne Control Panel which will automatically activate a 30-day trial period that you can use to test out the C1 .NET4.8 DLLs. You can also do the same on a fresh machine.
