Issue with Salesforce Ant migration tool v35

Hi,

I am trying to retrieve components from a managed package. I want to export configurable items from the managed package that I modified in my sandbox to another org. I am receiving the following error,

Failed to process the request successfully. Cause(UNKNOWN_EXCEPTION): null: More than 1 installed package named 'MyNamespace__MyPackage' exists in this organization. Use <namespace_prefix>__<pkg_name> to uniquely identify managed installed packages

I have only one package named MyPackage in my org and I tried both with Namespace and without it.

Thank for your help.

Regards
Mir

The error message seems to suggest you have 2 instances of the package installed (somehow) in your org. Can you post a snippet of your ant file here?

Hi, Thanks for the response. We are the ISV for the package and this is a manged package. I am not sure how this is possible to have more than one instance of the same managed package installed in the org. Please find attached my build and package files. --Akram
