Stack Upgrade error during extract kernel files

Hi All,

I am performing Stack upgrade 21 to 27 for Enterprise Portal. I am getting an error during extracting kernel files. Please help ASAP.

“The following problem has occurred during step execution:
com.sap.sdt.j2ee.tools.nondeployablehandler.NonDeployableHandlerException:
Could not handle non deployable component SAP KERNEL UNICODE WINDOWS_X86_64.

Could not execute file system operation with name Extract
and parameters archive:SAPEXEDB_600-20006747.SAR, target_dir:E:\SUM\SUM\sdt\data\kernel.

Could not extract archive SAPEXEDB_600-20006747.SAR to
directory E:\SUM\SUM\sdt\data\kernel because the archiver process did not run.

Could not start process E:\SUM\SUM\sdt\exe\SAPCAR.

Error while executing process E:\SUM\SUM\sdt\exe\SAPCAR.
