Hello @PAminA.35885 (Customer)​ Thank you for posting on our Community page!

I would recommend to completely uninstall the old agent and remove any files left over by it and then do a fresh reinstall. Please see our doc on this below:

https://help.okta.com/en-us/content/topics/directory/ad-agent-uninstall.htm#:~:text=In%20Windows%2C%20select%20StartControl,the%20Okta%20AD%20Agent%20folder.

Thank you for reaching out to our Community and have a great day!
