Setup has detected Opalis 6.3 installed on this computer. To continue installing System Center 2012 Orchestrator, uninstall Opalis 6.3, and then run Setup again.
One or more Opalis Integration Server 6.3 components is being identified as installed by Windows Installer.
Remove the following programs using Windows Programs and Features (Control Panel->Programs->Programs and Features):
If all of the above programs have been removed and no longer appear in Programs and Features then an artifact of one of the programs must still exist and is visible to Windows Installer. If this is the case, you can search the registry for each of the following identifiers and remove any that are found:
Depending on what artifact is causing Windows Installer to recognize the program as at least partially installed, you may be able to utilize MsiZap.exe to forcibly remove the remaining artifacts as an alternative to manually modifying the registry.
