Autoconfig on dbtier finished with error on dbtier 12.1.0.1

Hi,

I just upgraded the database from 11.2.0.3 to 12.1.0.1 and I have now a problem running autoconfig on the database tier.

N.B. :  This is all on a Windows 2008 R2

Here are my steps:

1. I installed the interroperability and prereq patches on the EBS.

2. I prepared and installed 12c ORACLE_HOME, prepared the listener, etc.

3. I installed the OPatch patches.

4. I ran the upgrade database that ran correctly.

5. I executed the sql parts for the patches installed in step 3.

6. I started the database and see that I can communicate with it from the apps tier.

7. I generated the appsutils.zip from the apps tier, transfered it to the db tier and unziped it.
