Executing Agent not Starting (service)

The Execution Agent is not starting for us for some reason. We are on AETL version 5.7.9.1, repository is SQL Server, and Operating system is Windows 2008 R2 Standard SP1. All aspects of the problem looks exactly same as posted on www.etl-tools.com/forum/advanced-etl-pro.../7321-agent?start=12 but the posted solution is not working for us so creating a new thread.

Below are more details around it.

1. We opened "Options" > "Execution" > Checked "Use Agent to Execute Actions" (Screenshot 1)
2. On Maintain tab, we clicked on Register Agent button and got message "Registered Successfully"
3. When clicked on "Start Execution Agent" we get error "Failed to Start AETL Execution Agent" (Screenshot 2)

We started researching on the community and found below potential solutions and results

1. Run app as admin and try again - Did not work.
2. Stop Execution Agent and try again - Did not work.
3. Try starting through windows services - We get error 1053 (Screenshot 3)
4. Change the service credentials to use admin credentials instead of local machine. Done. (Screenshot 4)
5. Put "quotes" in registry for executable path (per thread above). Done, did not help. (Screenshot 5)

Few more observations per other threads.

1. Green arrow (Execute now) on schedule tab does not work. Nothing happens.
2. Green arrow (Execute now) on design tab works perfect.

Please let me know more details you need. Thanks in advance for helping.

Agent only works once you have a valid licence

Thank you for letting us know. We are buying the tool. Loved the simplicity and power of it, and I must say that your support is awesome. Will enter the licence key may be this week or next sometime and will get back if we still face issues. Thanks!

I'm a senior user of this tool, and other tools and database tools and I can assure you, you will not find any other tool better than this tool for this price and the support they offer, it is superior.

I couldn't agree more. I am glad that I found this.

We purchased the license but still facing exactly the same issue. Please advise.
