My MacOS Version is 10.13.6. I have tried re-installing the Katalon Studio, but the error still occurred. Does anybody have any idea how I can fix this? When I opened the log it says: !SESSION 2018-11-16 15:43:55.616 ----------------------------------------------- eclipse.buildId=unknown java.version=1.8.0\_181 java.vendor=Oracle Corporation BootLoader constants: OS=macosx, ARCH=x86\_64, WS=cocoa, NL=en\_CA Framework arguments: -keyring /Users/\_\_\_\_\_\_\_\_/.eclipse\_keyring Command-line arguments: -os macosx -ws cocoa -arch x86\_64 -data config -keyring /Users/\_\_\_\_\_\_\_\_/.eclipse\_keyring !ENTRY com.kms.katalon 4 0 2018-11-16 15:43:56.249 !MESSAGE [SCR] Component definition XMLs not found in bundle com.kms.katalon.

Sorry for the inconvenience, I tried to open it from the installation window instead of in the application folder. ![](https://dub1.discourse-cdn.com/katalon/uploads/default/original/1X/14249a3480db9e222a1c8fb30d006abb0e39d670.png) Thank you.
