After installation (CD + patch 01), the system can be started. Without having imported without settings (eg, locations, or the like.) Changed, the application is terminated. When you restart the system of Pinnacle startup screen appears darkened; it is now no longer to activate function.
It was noted that after complete removal of all Pinnacle components (directories, files) the installation screen indicating a Pinnacle component as already "Installed" (with a green check mark). The corresponding directories could not be deleted by Exprlorer and had to be removed by the "Remove".
After uninstalling the previously used Pinnacle version 16 were tens (!) Directories and files were not deleted ...
The contact with the acquisition Corel Support ("one-time installation or activation Support" within the 14-day) resulted in the release:
"The problem is not covered by warranty support. ... For any questions or problems not covered by the definition of 'basic questions about the installation' fall, we ask you to purchase a corresponding Suppurtfall."
