I wrote a program in Delphi for sending an email.

Problem:
The people who are to use the program do not have administration rights.

If this program is now executed, then the message appears:
class not registered

Is it possible to use easendmail without registering the file "easendmailobj.dll"?

Hi, you should distribute the DLL with manifest file like this:

https://www.emailarchitect.net/easendmail/sdk/?ct=object_reg_a 

If you need further assistance, please contact our support email address.

Embedding the manifest worked.
Thanks so much.
