Jeff,
You may want to use /Utilities/Console and look at /Library/Logs/Adobe/Installers to see where the failure is actually occurring. Even though it's one install package, it's installing each application in sequence. If only one fails (and all the others succeed) you'll still see the message you received. There can be a lot in the logs, but you can use the Spotlight field to filter out the lines with "return code." Anything other than "0" (zero) indicates something that didn't complete. You can also look for words like "error" or "fail".
There are a bunch of things that can cause an error. I've sometimes had a problem with packages that include a lot of updates but rebuilding them seemed to fix it. Finding out exactly where the error is happening is a big help when you contact support.
I realize this isn't a solution, but hope it helps.
