The first time I went into CS5 from LR3 I was given a message that I needed to upgrade to ACR 6.1 I ran the update from the help menu and was presented with 2 updates ACR and Bridge. I ran the updates and they both just say failed on the Adobe updater screen. I have tried everything I can think of and used the online support with no success. I have called Adobe Tech support but it has to be the absolute worst technical support in existence. I was escalated through the ranks only to land with a technician who wanted to know if Bridge and ACR were a part of CS5. I was finally given a case number and was told it would be escalated to the highest level but that I would have to wait 3 or 4 days for an answer. Got an email from them with questions I had already answered and suggesting i try it again. Called them back again today and so far have spent 2.5 hours mostly on hold and escalated to the "Concern" department. Fine fellow there also wanted to know if ACR was a part of CS5. Was then put on hold and then hung up on. I am now on hold for the last 20 minutes with customer support trying to get this sorted. Hoping that someone on here might have had the same problem or know what might work to get the updates to install.
