It may well be that you still have some protection software (anti-virus, firewall, anti-spyware and the like) running, that is causing this. Try to turn of these programs before installing.
I am running Microsoft One Care for virus protection. I'll turn off and try
again, thanks, good thought.
I turned of Microsoft One Care and also my firewall and tried to auto update through Premeire again, and it failed again, so virus protection or firewall is not the issue.
I called Adobe tech support by phone but our connection was poor (overseas?) and I was eventually disconnected midway through the conversation. First the tech was suggesting to me that Adobe Premiere perhaps is not suitable for a Vista 64 operating system. When I explained it was, then he suggested pehaps I was downloading the wrong version of the update. I was explaining that there is no 64-bit update choice on Adobe.com download, only Windows or Mac choices, plus the auto update should know what to download itself, when we were disconnected.
I have 50gb free on the install drive so I don't think it's running out of disk space, and 4gb RAM.
There's nothng queer about this PC, it's a new Vista 64 pC and the only software on it is Adobe Web Premium and Adobe Premiere, plus Microsoft Office 2007, and Filezilla.
I don't have any suggestions of how to solve this issue with the current information, but one thing is clear: You got a call center employee when calling Adobe TS that was very new in the job, did not know what he was talking about and did not know where he put the Q&A list he should be using. It is a shame that Adobe does not pay more attention to the quality of support.
Can you post a screenshot from Process Explorer, while running your normal applications and PR running. Maybe that will reveal something. Also have a look here for where to find it and other tips on troubleshooting: http://forums.adobe.com/thread/416679
This is not just a Vista 64 PC problem.
The installation does not work on XP either. The installation behaves as if it worked but each time i ask any of my Adobe programs to check for updates, the updated wants to install Media Encoder 4.1 update.
