While converting i have uninstalled the purchased "QuickReportBuilderXE5.06" software and installed "QR6-RAD-10-2-Tokyo". I have compiled the my project successfully. But We are getting error while opening our application. Error Message: "Project Test.exe raised exception class EFilerError with message 'A Class named TQuickRep already exists'. Why we are getting this error...? how to resolve it?... Thanks in Advance. Regards, Mahesh Babu. Share this post Link to post
