I'm posting my experiences with this error because it can hopefully help other people. I was getting the same error during the Configure LiveCycle ES (1 of 3) screen after clicking the Configure button. It would fail around 75% with a prompt saying error code ALC-LCM-000-000 and could not clean working directory. The progress log would indicate the failure at executing merge scripts for adobe-livecycle-native-weblogic-x86_win32.ear. I was installing LC ES 8.2.1 SP3 + QF 3.19 with the Forms and Output components on a Windows 2003 platform.
Rename working dir (LC support suggestion)
Rename c:\adobe\livecycle8.2\configurationManager\working to be like working.old. Re-run ConfigurationManager (CM). Didn't help since I saw the same error message.
Clicked Configure again on and it went 100% without any problems. The rest of the install went just fine.
Reinstall Adobe LC ES 8.2
I was getting the same type of error on another box, but clicking Configure wasn't getting past 75% again.
Reboot of the box didn't help on the next attempt.
Reinstall LC ES 8.2 worked
Used the Add/Remove programs to remove Adobe LC ES 8.2
Reinstalled the software with SP3 + QF 3.19.
Ran CM again and I was able to get past this error.
