As it says the service is used by another service. That means you will need to set your PC to Allow the CMS service, it will then be assigned a service and run. That is the error I was speaking of. It can be caused by the OS or the AV so check both.
Thanks for replying, finally found the problem, had 2 Content manager folders, how I don’t know but once the 2nd one was gone I was able to import all the files and get smart content working. Thanks again. I feel a bit silly but at least found the problem.
