NOTE TO ALL HAVING ERRORS REGARDING 'SETTINGS.INI UNABLE TO SAVE' OR MORE COMMONLY KNOWN AS THE '3X ERROR POP UP SCREEN'
Rocketdock needs to have complete admin rights to be able to modify any data that the user demands into the dock. For example, viewing/modifying/replacing settings,icons,etc.
To give it complete administrator rights, follow the steps below and your errors should disappear.
1. Go to the drive you have RocketDock installed and locate RocketDock folder.
2. Right click on 'Rocketdock.exe' and select properties.
3. Click on the 'Security' tab and select 'Users (XXXX-PC\Users) and select 'Edit'
4. Another window should open named 'Permissions for Rocketdock'
5. Select the desired user (as selected in Step 3) and make sure 'Full Control' has been checked.
6. Click on 'Ok' and the window should close. Now you're back to the window you opened in 'Step 3'. Click 'Ok' here too.
7. Exit rocketdock and restart it by right clicking on it and selecting the option 'Run as administrator'
If problems still persist, please report them here with a detailed explanation (preferably with screenshots) so me and/or Hamed can look into it and revert to you as soon as possible with a probably solution.
Cheers,
