During replay of a Flex test I receive the error "License not present. With trial version only limited replays are allowed"
The error message is presented during playback because the "automation.swc" library which is used to test the user interface automatically, is an Adobe proprietary library and you need a Flash Builder or Flex license to run an automated test using these libraries.
This message is presented by the application itself and is not generated by Silk Test, as such we can only provide limited support.
Please see the following Adobe community post: https://forums.adobe.com/message/4083435#4083435 which demonstrates how to locate the information to be specified in the flex-config.xml.
