I have an ms access .mdb file a customer gave me. His programmer is no longer available and he needs additional coding to be done. When I try to open the file (I have Access 2007) I get the following message: You do not have the necessary permissions to use the 'c:\temp\workers.mdb' object. I have a program that shows me all the workgroup user passwords, group IDs, and user passwords. However, the file isn't asking for a log in or password. How do I give myself the necessary permissions?
