I am currently using 10.0.2, DBVIZ gave me the option to upgrade, and it downloaded the dmg, mounted it and executed the installer.
I selected 'Yes, update existing installation' and clicked next.
In the next window EULA appears, with 'I do not accept the agreement' selected. At this stage I cannot do anything, I can't accept the agreement nor click the back or cancel buttons. The installer just hangs. I have to force quit the installer and everytime I get stuck at the same position.
I have a log it generated to send to Apple, however I haven't attached it here as it is around 1mb in size, and it might contain some private details.
Let me know if you need more help on this.
Yes, the ignore app does not work for the installer, but it helps on other issues I have while running it afterwards.
