Push and path of point 0 which is the title of the set file. Contact the batch file with full pathAnother remedy is calling the batch file with complete path. Contact 'F:- Large Packets -kitterengineCommonTemplate.bat'The distinction to very first solution is definitely that after end of batch file Design template.bat is achieved the group processing proceeds in batch script made up of this command range.For the current directory examine above.
