Manager on new PC

Copying files is not the way to migrate Manager. The proper way is to make a backup (on your USB would be OK), then download and install Manager to the new machine. Then use the Add Business button and Import Backup option on the new machine.

Try doing a restore by navigating to a folder that contains all those Manager files. Since I don’t know what they are, I don’t know if Manager will recognize one as your data file. Understand that the application itself contains none of your data. It only calls the data files.
