The auto start of the aquasuite uses the Windows task scheduler. Maybe check if you can spot any obvious problem there.
First thing that you should try is to simply raise the start delay: run the aquasuite with admin rights and in the aquasuite -> settings tab you can change the start delay to a quite high value like 10 seconds just for a test. If that helps, you can still try to lower the value step by step until the problem is back again. It is possible that the aquasuite does not run immediately after the system start because some other required stuff is not loaded yet. You could take a look into the Windows event manager. It might be possible that there are even error logs for the aquasuite because of such a problem.
If it is just a configuration problem with the task scheduler it often helps to run the aquasuite with admin rights, disable the autostart in the aquasuite -> settings tab and then close the aquasuite. Check the task scheduler for a "aquasuite autostart" entry and remove it manually if it still exist. Do not remove the "aquasuite service helper" entry.
Start the aquasuite with admin rights once again, enable the autostart, close the aquasuite and check that the "aquasuite autostart" entry exists in the task scheduler. If so, restart the system and hopefully it works now.
The previously mentioned start delay could also still play a role.
