I am trying to open an MS Access datasource in ChemFinder. In the Database tab of the Form Properties dialog box in ChemFinder, I can see the name of the table in the Access datasource, but I can't see some of the fields in this database.
Check to see if you disabled (or never set) the Permissions to the tables that could not be opened in ChemFinder. You need to open the database in MS Access, and choose User and Group Permissions from the Security option in the Tools menu. You then need to put check marks in all the Permissions options like Read Design, Modify Design, etc. for any table that will not open in ChemFinder.
