How to install applications created on my server

I created an application but I can not install it on my server.

Have you tried built-in deploy? For example Deploy to IIS: https://www.radzen.com/documentation/deploy/

Thanks for the answer.
However I would like to install on an external server, like send the files via FTP.

In this case you can use Deploy to FTP or Deploy to ZIP and unzip the content where it should be.
