I am developing a VB.NET project with C1 for .NET 2.x. When I run the program, this message pops up. How can I remove this pop-up?

Hi,
To use C1 controls in your application.
(1) You should have a valid license key activated in your system.
(2) You should have a licenses.licx file embedded in your application (containing entries for all the C1 controls used).This popup is typically seen when one or both of the preceding steps are not taken.
Regarding (1), if you already have an old license key, you can activate it in your system using the C1LicenseActivation utility. If you do not have a license, you will need to purchase a new license by contacting the US sales team at (https://www.grapecity.com/contact)
C1LicenseActivation: (https://cdn.grapecity.com/ComponentOne/LicenseActivation/EN/C1LicenseActivation.exe)
FYI, starting from the 2020v2 release, we have updated the format of our license keys. The latest format is a 19-digit key and the old format was a 28-character key. The old controls you are using only recognize the old-format key. Therefore, once you purchase the latest license key, you will need to follow the steps in the link below to generate an old-format key.
Regarding (2), you can follow the steps mentioned in the link below to generate the licenses.licx file

JFYI, the C1 controls you are using are very old and already out of support from our end, meaning they will not receive any new feature updates, bug fixes, or new controls. Therefore, our suggestion would be to migrate to the latest .NET FW 4.5.2 / 4.8 C1 controls to avail all the benefits.
Best Regards,
