The pdfMachine merge history allows you to look at the results of past merges. It is stored in an SQL database file in your user appData directory. You will need to delete it or restore it from backup (if you have made one). If you don’t have a backup then you will lose your merge history but your profiles will all still be intact. If you get an error such as “SQLite error no tables” or " SQL logic error : no such table" then this file is corrupted.
- Close pdfMachine merge
- Delete/Restore the file mergedb.s3db in directory C:\Users<user name>\AppData\Local\pdfMachine merge
