Im getting this Error:

What version of Zbrush are you running? And Zbrush dropped support for XP, it’s no longer a supported OS. You might need to upgrade.
The reason you’re getting that message is that you already have an instance of ZBrush running. Go to the Task Manager (the easiest method is to right-click on your Task Bar and choose the option to Start the Task Manager). First, look at the Applications tab. Is ZBrush already listed there? If not, go to the Processes tab and look for ZBrush there.
In either case, select ZBrush when you find it and then click the End Process button. This will kill any phantom instances of ZBrush.
However, as MentalFrog said, ZBrush 4R3 and above require Windows Vista or Windows 7. We can no longer support XP for those ZBrush versions.
