Error:
Please start/stop the product to proceed with upgrade.
Possible Cause:
Some background tasks might be running in the background.
If the log folder files are not updated correctly by default.
If you perform more than one consecutive upgrade without starting/stopping the services after each service pack, you will encounter the above error.

Step 2: Navigate to the Details tab in the Task Manager.
Step 3: Place the mouse cursor on any of the header columns and click on the Select Columns option after right-clicking.
Step 4: Select the Image Path Name column.
Step 5: Search for any (\ManageEngine\ADManager Plus) applications. If any are running, kindly end the process.
Step 6: Navigate to \ManageEngine\ADManager Plus\bin and open the command prompt as an Administrator.
Step 7: Execute the command wrapper.exe..\conf\wrapper.conf and the product will start.
Step 8: Log in to ADManager Plus to check if all the modules are populating.
Step 9: Follow Steps 1 to 5 again and ensure all ADManager Plus processes are closed.
Step 10: Proceed with the upgrade.
Step 11: If the above solution doesn't work, rename the logs folder, start the product once, stop it, and then proceed with the upgrade.
