If you encounter the error listed below, it is because you have not created the AyaImport.exe.config file as directed in the AyaNova v3 Manual in step 3.b.i

Connection type: "" not valid in application configuration file means there is no AyaImport.exe.config file, therefore the CEImport utility has no idea where your AyaNova database file is

Recheck your steps, and create the AyaImport.exe.config file as directed in the manual.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.
