I had an issue while upgrading from Vcenter Protect 8.X to 9.0:
When the installation program called the database setup tool I selected to use an existing database. After pressing next nothing happened and the Database Setup Tool Window got frozen. It behaved strange in that it was unable to receive the focus, could not be activated, moved or resized. It seemed to me as if it had opened a modal dialog which had to be ackowledged. But there was no dialog. The only way out of this was to kill the process with task manager. Afterwards the installation program performed a rollback with the effect that even my 8.0 Installation got lost.
Any idea appeciated !
