Hi My testrunner.bat file for SoapUI PRO got corrupted. Where can I download this file from ?

Easiest solution for you, as i have no idea what version of SoapUI PRO you are running is to go to this site if you have the latest version. Or this if you are looking for something old. 

Then install it somewhere other than your installation and then copy the testrunner.bat to where you need it then uninstall the newly installed SoapUI Pro, this is so you get the right paths in the batfile.

If you like to tinker on the other hand you can just download the file from GitHub and modify the paths for your version/system.
