Windows could not start the Veeam backup service service on local computer Error 2: The system cannot find the specified file

Welcome to the community @seshasai2809.

Sorry, for my first input, which i have now removed (i mentioned a problem regarding a refused connecting after upgrading to V12.2 →  No connection could be made be because the target machine actively refused it 127.0.0.1. | Veeam Community Resource Hub).

Is this error after a fresh installation or after an upgrade to V12.2? Please provide us some more details, so we are able to help you with your issue.

Also, it’s an option to contact the support team.
 

Hello,

You can register a ticket with Veeam support, but have you already checked the Windows Event Viewer to see if there is a log with more information?

Also, you can check if the Veeam SQL service is running.
