In my case, I had this problem running Openerp 5 over Python 2.7.

I have installed Python 2.6 making them both coexist. But the problem is
that the 2.6 installation, doesn't have the needed addons installed. The
key problem is PyUno ("uno") is an open office bridge, needed for the
report_openoffice, which has some dependencies with other modules.

The problem comes from the old server which has been compromised, so I
had to migrate in a rush to another server

Please, help. I'm not prepared yet for OE6, since a number of modules
must be upgraded to 6 before I could migrate.

  list them with their versions)

  Problem:
  -------------------------------------------------
  1. I installed OpenERP 6.0.0-rc1
  2. I clicked on the "Start Configuration" button that appeared when I first logged in
  3. I hit next (I've tried several times and it doesn't matter if I use the simple or the extended Interface)
  4. I hit next (again, I have tried by entering in valid data and have tried with the defaults)
  5. I select/check all of the applications and any of the "Industry Specific" applications and then hit "Install"

  I then get the Following:

  An Application Error has been reported.
  Let me fix it
  Fix it for me
