Shashavali ,

the administrator has restricted access to any sub folder under C: drive.

is it possible to load the driver from any given file location?.

Mr_Bro 

If the above file is required, then I believe your system admin can fulfill your request, just please check.

Any user libraries placed under SOAPUI_HOME/bin/ext directory are loaded by the tool automatically.
