I have followed all instructions on how to split a database so that multiple users can use at once. When I initiate the Access Database > Database Splitter & pick "Split Database" it requests the a file location to save to. Once I do that (I pick a location on my hard drive) it throws up this message "The database engine could not lock table 'Materials' because it is already in use by another person or process". I don't have any database open on my hard drive nor any network drives. I have tried many suggestions found on internet searches, but have had no success. Hoping someone on this forum can help. This is greatly needed in my organization. I appreciate any help in advance.
