Your Experian Batch isn't configured correctly.
To check, go to the addressValidate\runtime folder in your Data Studio installation (e.g. C:\ProgramData\Experian\addressValidate\runtime).
Using the Command Prompt, run BATWV64.EXE (the Experian Batch API test harness). You should see the list of available address layouts. For Use layout number enter the number of the layout from the list that corresponds to a country you have configured.
If you get an error, Experian Batch hasn't been configured correctly. Contact us for help.
By default, the qaworld.ini contains all the address and component layouts used by each data set.
You shouldn't delete these layouts but you can make modifications as long as the layout continues to be valid (i.e. it works in the test harness).
If the qaworld.ini no longer contains address and component layouts, we recommend rolling back to the default version which can be found in addressValidate\templates.
The address validation engine has a hard limit of 32 handles. If you reach that limit, an error occurs and a message will be shown on screen: 4003: An error occurred in the Address validation engine: 'No free API handles' (-8610).
The number of handles that are currently in use is reported in the log.

12:36:06.272 [Thread-100] INFO com.experian.datastudio.Qas.BatchObjectLayer.QasSearch - Batch handle count decreased from QasSearch: 28
Users will have to wait for address validation engine handles to be available before continuing.
