ExceptionDeployer, Acrobat install fails (1603)

Hi,

My first time experimenting with CCP, under Windows 7 x64, I made a package that includes all x64 Creative Cloud products and am now testing install. I read the Exceptions instructions pretty carefully and hopefully am doing this in a valid way.

From a "Run as administrator" command prompt, I'm running the command ExceptionDeployer.exe --workflow=install --mode=pre --installLanguage=en_US

It fails with Return Code 2 in CMD ... when I check the log file, it appears to launch ok (no messages about privileges), but then gives:

4/19/2013 16:08:51 [INFO] ExceptionDeployer - The process return code is (1603).

4/19/2013 16:08:51 [ERROR] ExceptionDeployer - Exception deployment failed for payload (AcrobatProfessional11.0-mul)

Anyone have a thought what might be the prob, or what I could try next?

Could I just have a bad Acrobat installer package for some random reason?

Perhaps I'll try making a new CCP package with only Acrobat and see what happens.
