Hi Vikas 8517,

• Can you delete Delete below file if exist, 

C:\Windows\System32\config\systemprofile\AppData\Local\AutomationAnywhere\registration.properties

and then uninstall and reinstall the Bot Agent and check again?

If this does not help,

• Open Task Manager (as Admin)
• Click Services
• Click on STOP on "Automation Anywhere bot" running Service
• Re-install bot agent

Hope this helps!

Fred
