Are you trying to move the Painter launch icon to a different location to make it easier to use?
If so if you can browse to your Mac HD/Applications/Painter folder do you see the icon for Painter?
If so what happens when you double click it?
Can we first try an uninstall and reinstall to make sure everything is where it needs to be.
First could you remove the Corel Painter X application folder by dragging it to the Trash icon in your Dock, Then go to the User Library, Application Support, Corel folder and remove the Painter X folder by dragging it to the Trash.
Next go to the User Library, Preferences folder and remove com.corel.PainterX.plist by dragging it to the Trash.
Once you have done that empty the Trash and then restart.
When your machine reboots try reinstalling again using the default options and then reboot when finished and try to launch the program.
Let me know what happens.
Just look in your Mac HD then go to your username and you should find the Library folder.
Dont worry about the accept till we finish.
