Error while installing a packaged application

Question

Hi
I am getting the following error while trying to install the "Sample Master Detail" application in my apex oracle account on the web. All the others install without problem. What could it be ?
Thanks
Juan

Hilary - I asked our DBA to open a SR, the number is SR 3-6553142501 : Unable to install packaged applications in Oracle Apex
Looks like apex.oracle.com has been upgraded to 4.2.1. When did this happen?
I am almost positive that I was able to install packaged apps on apex.oracle.com even when it was on 4.2.0.00.27 (same as the publicly available version) but not on my instance. But now since the versions are different, the support person is pointing to the different versions as a cause! This is what I was afraid of. To be honest, given that I was getting the error on my instance but not on apex.oracle.com, even when both systems (mine and apex.oracle.com) was on the same version of APEX, I am not very hopeful that the 4.2.1 patch will fix my situation since the root cause has not been identified. I just don't want to wait for 4.2.1 to be released, apply it and find out that the issue is still there. Can you share the list of bugs fixed in 4.2.1 to see if any of them may apply to this situation?
Any other ideas? What diagnostics can I provide to help you get to the bottom of this? Frankly, Oracle Support, as I found in the past, is not very well qualified to resolve APEX-related SRs. Can you please assist or direct Support appropriately? Thanks, appreciate your help.
Since I have the Builder app installed in my instance, I inspected the final page of the packaged app install wizard (4000:83) to see what APIs it uses and ran it manually as SYSTEM. This is what I get. Does that help narrow down the issue?
