NXPowerLite comes with an uninstall script (uninstall.command) which should be run to completely remove NXPowerLite. It is located in the Applications/NXPowerLite directory. If the script is not used to remove NXPowerLite Desktop then you are likely in a situation where you cannot completely remove the old version and/or install newer versions.

If you have deleted it then you can download and try it from the corresponding downloads v7 Uninstall script | v8 Uninstall script | v9 Uninstall script
If the script does not work or you continue to see problems then please follow these steps:
This problem occurs during the installation of NXPowerLite Desktop for Mac if it detects an incomplete uninstallation of a previous version of the software.
If this happens, the installer will put up the error message and not allow installation to continue.
The solution is as follows:
- Launch a Terminal window, which can be found in Application -> Utilities.
- Run the following two commands:
- sudo pkgutil --forget 'com.NeuxPower.NXPowerLite.pkg'
- sudo pkgutil --forget 'com.NeuxPower.NXPowerLite-Desktop.pkg'
Note the sudo command will probably prompt for an administrator password, and that the command is case-sensitive.
