Access - can't save objects, says I need exclusive rights to the file

I have a client I'm helping with a database.  There are about 12 people who use this file.  The file is split into front end and back end.  All employees access the same front end.  They are trying to create a new query or report, but are given the error message "Microsoft Office Access can't save design changes or save to a new database object because another user has the file open.  To save your design changes or to save to a new object, you must have exclusive access to the file".  

Nobody is opening the file with exclusive rights, and to create a simple query, they don't need this.  Any help is appreciated.  Thanks!

This is the reason why you're getting that error. Access manages a lockfile, and if there is more than one user in that lockfile Access won't allow changes.

Further, multiple users should NEVER share the same FE File (but they should all connect to the same BE file). The chances for corruption (data or otherwise) is much greater with multiple users sharing the same file, and it's just not good deployment practice.

To fix this, create copies of the FE and install a copy directly on each machine (either in the Documents folder, or the user's AppData/Roaming folder or AppData/Local folder).

User should then be able to open their own personal copies of the FE and create those queries.

Then, by no means, should the individual user tamper with this. If they need to create ad-hoc reports, create a simple app connected with read-only access to the backend tables, and pass each user a copy. If a user creates a report to share, have one person to organize updating the common frontend after some kind of approval.

A frontend can be distributed automatically by launching a script. An example is here (can be reduced somewhat for your purpose):

Recently i had bizzare locks due to Antivirus...disable and check again...
