Answer 2: We updated our server with this version without problems, I recommend you make a personal instalation (if you are using IIS) and use an administrator account for the Qlikview services (this account must be add to Qlikview administrator group)
If you are using Internet Information Server (IIS), the standart installation doesn't create the virtual directories in it, so, you have to do a custom installation if you wanna a correct functionality.
The actualization I did was from 8.5 to 9.0 SR1, I had to uninstall the old and configurate the new one after. There are a few changes in the new version (management console), so, you'll have check it out.
I think you should register in Qlik Community with your appropriate rights (Customers, Partners ...) and then sign In before download. If you're a new prospect I think you can only download the Personal Edition.
Did you create you QlikCommunity Account with your professional mail ? For example I'm a member of Keyrus, a French Partner of QlikTech. I've create my account with my address firstname.lastname@example.org and the next day my partner access was automatically provided by a bot.
If it's still doesn't work, you should ask directly to QlikTech
