  Hi thank you for your forum post.
  
  Can you please provide some further information as to the steps taken to experience this "The key already existed in the dictionary" error.
  
  Is it occurring during a comparison? If yes, what are the data sources for the comparison, for example source = scripts folder, target = live schema.
  
  Full version number of Schema Compare for Oracle you are using?
  
  Many thanks
  Eddie

  I am running compare between two Oracle db instances. Both dbs are the same version of Oracle. When registering databases, before it even runs compare, I am getting that error when using Red Gate 4.0 of Schema compare 32bit

  Thank you for your reply.
  
  Would you please increase the minimum logging level to verbose logging as per this help document:

  Thanks for your help, older version of software did not require access to some of the system tables, I guess current one does, so once I switched id I was using to the one with more access rights, issue was resolved, thanks a lot for your help.
