Cannot find curllib.dll Please re-install this application

Hello,
I have this error with license for Adobe. I can’t activate it and I don’t know why. It is my first software with a license so I am newbie with this. I contacted the Adobe support but no answer. Can anyone help me to fix this? Please tell me the steps to activate my software.
Thank you!
