Hi

I have struggled with this Error Code: A12E1 for several hours today. It seems like my problem was related to installing Mac OS with my disk formatted as the Case Sensitive File System flavour of HFS.

Background:

I made a fresh install of the latest macos (Mac OS 10.9 Maverick). I just could not understand what to do, also tried to look for answers here: http://helpx.adobe.com/creative-cloud/kb/a12e1-error-downloading-creat ive-cloud.html

I tried

1. starting up in safe mode
2. use my system username (to admit installation on the mac) instead of my First name and Surname when promted in installation, as I was thinking it maybe created some problems
3. Copied the installation file from my mounted disk file (.dmg) to desktop before trying the installation)
4. Tried the cleaning tool provided by adobe

No luck in any of it

Anyway - suddenly i found this: http://helpx.adobe.com/creative-cloud/kb/unable-login-creative-cloud-248.html

Even if this solution did not fit to my problem description I tried to install the ApplicationManager7.0 for mac.

And then I got an error message telling me that ApplicationManager could not install on a case sensitive file system

OK I aborted the install of ApplicationManager, decided to see if this file system reason was the problem for my Creative Cloud installer too. And I used the program iPartition to convert my file system to a case insensitive file system (still HFS).

After starting up my mac again on my converted-to-case-insensitive-HFS , I installed Creative Cloud installer without problem.
