I am using Windows 7 64bit operating system, before ideCAD 7 64 bit update I was using ideCAD 6 32bit. After installing and using the ideCAD 7 64 bit update, I removed the ideCAD 6 32 bit version from my computer. Now, Windows does not open files with .rpt extension, even if I try to say "Open the file with" and select the iderpt.exe file from the ideCAD folder, it does not work.
