Not able to generate Report in Test Runner on SOAP UI

Hi All,

           I am trying to create report in SOAP UI while I do the Test Runner. I am getting  error and report is not generating in the particular folder. Looks access denied. Please find attached screenshot for error and also included in the log4J file. Could some one help me on this.

  Configuring log4j from [C:\Program Files\SmartBear\SoapUI-5.3.0\bin\soapui-log4j.xml]
log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException: global-groovy.log (Access is denied)

Thanks

Sakthi
