Could not update currently locked by user

Hi guys!
I have an application issue here in Microsoft Access. I met an error while working. The error message went "Could not update; currently locked by user ‘admin’ on machine ‘PC04’." I pasted below the error message full text for your full view of the application issue.
![ERROR [GY000] [Microsoft][ODBC Microsoft Access Driver] Could not update; currently locked by user ‘admin’ on machine ‘PC04’.](https://www.techyv.com/sites/default/filesx/users/pameladir150/Application-issue-here-in-Microsoft-Access.jpg)
ERROR [GY000] [Microsoft][ODBC Microsoft Access Driver] Could not update; currently locked by user ‘admin’ on machine ‘PC04’.
This error message that was displayed on my screen let me think for a long time on how can I solve the error. I already checked all the aspects the error message states, but I still get same error message.
Please share some ideas on how to solve this application issue. Thanks a lot guys for reading my post.
