What version of CentOS are you running? We only support CentOS 6.9+

In the image you provided, I see something in your license key that seems incorrect:

Can you please check that you are using the proper license string? Also, you’ll probably want to make sure to use single quotes around your license string as it could contain a $ character which doesn’t play well on the command line.

Thanks,

Rob

HI rtadlock ! Thank you for coming back. I know the problem. I used double quotes marks to cause the problem. Solved with single quotes marks
