So I tried the trial version but my serial number didn't work I guess because it's for a CS5.5 Web Premium product. I also tried uninstalling my current version of FB4 Standard, uninstalling CS5.5 and starting from scratch without any copies of FlashBuilder in my Applications folder and that didn't work, same error log message. I ended up reinstalling my original copy of FB4 Standard so I could continue working.
The odd thing is when I went to my MacBook Pro and uninstalled the copy of FB4 Standard I have on there and installed the CS5.5 FlashBuilder 4.5 Premium it works and started up fine. So I'm guessing there's something specific about my iMac setup that's preventing launch.
I was looking at my FB installation details, don't know if this matters but I'm running the standalone version:
Adobe Flash Builder Localized Standalone Feature 18.104.22.1687662 com.adobe.flexbuilder.feature.standalone.nl1.feature.group
Unfortunately it's the weekend (holiday in US too). I like the weekend for trying to get these things setup but I'm on my own and feel I'm out of luck until the work week starts.
If anyone from Adobe is reading this with a beer in one hand and hotdog in the other (or burger or veggie burger or bbq chicken leg) on a hot memorial day and have an idea on how to fix this I'd really appreciate your advice. Thanks!
After a long call with very helpful Adobe Technical Support, I thought I should try and just run the basic Eclipse and that didn't work either. I thought about the fact that my iMac configuration was migrated from a previous iMac using Time Machine and that I'd probably junked up the works even further over last year or so, not to mention whatever I brought with it when I migrated.
The solution was to back up all my docs, work, ect. and erase my iMac and reinstall the factory settings for 10.6, which I was looking forward to. A fresh, clean and zippy machine is now running Flash Builder Premium 4.5
