Troubleshoot the installation

If you are installing AVEVA Real-Time System (RTS) on a Windows Server operating system (OS) after previously uninstalling RTS, you might get a message that the product "is already installed" when you try to re-install RTS. If you continue to receive this message after you confirm that RTS is not installed, an unrelated corruption in the Windows registry may have caused a problem during the RTS uninstallation such that the RTS registry keys were not properly updated or removed. You may be able to fix this problem by cleaning up the RTS registry keys.
