  • Hello,

    If your installation is LoadRunner 2020.3, please note:

    For version 2020 SP3 Several Flex jar files are not installed with VuGen due to security considerations. They are located in the DVD\lrunner\Common\blazeDSclasses or DVD_PC\Setup\Common\blazeDSclasses folders. To create and run Flex scripts, manually copy these jars to the <VuGen root>\jars folder

    Regards, 

    Levente.
