       I get the following error when launching the controller. I have removed & reinstalled the software multi times. Any ideas?

May I know the Java version installed on your PC?

Is it the first time to install and run the controller on your PC?

  @pcsat 

do you delete anything by accident? error in the launching says 'install failed'? 

if software controller, did you ever backup anything?

maybe you install again in the same path. i think install in the same path does not delete anything but somehow repair your missing stuff? i never tried this just a guess from my past computer experience.

After rebooting system when it still wouldn't run i reinstalled the app with the same affect. i had added two sites recently that was not backed up, so would like to resolve the issue without losing data. The install / reinstall is using the default path.

If you enabled Auto Backup on your Controller before, the backup file will be saved in your installation path. But if you haven't enabled Auto Backup nor manually backed up the configuration before, I'm afraid that you may need to re-configure your network eventually. Hope you don't have lots of settings to be configured.

As you mentioned that you tried to reinstall the Omada Controller, may I know how you reinstalled it?

Did you firstly uninstall the Controller and select YES when it's asking to retain user data, then reinstall the Controller in the original path?

Note: if you select NO, all the user data will be cleared, you will need to start from scratch to set up the Controller.

Edit:

If you still fail to launch the Controller on your PC at present, I'd like to escalate your case to the TP-Link support team to look into the issue.

Please feel free to let me know if I can be of any further assistance here.

i have installed the controller software on another system, is it possible to copy the user data into this system from the non working system? im not sure if i had the auto backup enabled. Can i check for a file in the path of the installation? if so what is the file name?

I don't think the user data can be migrated across the system.

If you are using Windows OS, the auto backup file will be saved in the data folder under the installation path.

For your reference, my installation path is C:\Users\Administrator\Omada Controller\

The backup file is saved at C:\Users\Administrator\Omada Controller\data\autobackup

To try locating the controller failed to launch issue, would you mind me creating a support ticket via your registered email address, and escalated it to our support engineer to look into the issue?
