After migrating our aem Author instance from a physical server to a VM on a Gaap server (Windows 2016 server standard), I am unable to start our AEM Author windows service and receive the error: Windows could not start the AEM Author service on Local Computer. Error 5: Access denied . I tried deleting the service and reinstalling it and receive the same error when running the installer through the CMD prompt as Administrator. I am still able to start the instance through our start.bat file, and it runs without errors. There is no additional context in the Windows logs. Has anyone run into anything similar? And is there a way to remedy this issue?
