There is a file that needs to be backed up from the old installation. The file path is C:\Program Files\MARKS USA\MarksUSA.mdb
Make a copy of the "MarksUSA.mdb" file on a disk or removable drive. Install the iDat software onto the new computer.
Overwirtie the "MarksUSA.mdb" file in the new computer with the saved file from the old computer. The file path would be the same C:\Program Files\MARKS USA\MarksUSA.mdb
Start the software as normal and enter your password. You should see the same information that existed on the old computer.
