Add a string called “DumpDir” to the registry under “HKCU/Software/IBM/Lotus Quickr/Desktop Integration” The string value should point to an empty directory on you local machine. This registry value is read only once so you'll have to re-login to Windows to get it recognized.

Not all responses are saved to files here but e.g. the getBusinessComponentsByPage response will be saved in a file called libraries.xml.

You can open the XML file in Internet Explorer which does a good job at reporting XML errors.
