Error Message due to missing or corrupted MSysACEs

MSysACEs are the files in system tables that contain information about access permissions and privileges assigned to specific database users. These files are primarily used for the operations performed in the Access database and are also used to keep a track of all the database components. Corruption of MSysACEs files primarily occur due to MS Office malfunctioning, operating system damage, virus hit and more. Once the file is corrupted, MS Access database becomes inaccessible. In such circumstances, an ideal solution is to restore the data from an up-to-date backup. However, if no backup is available or backup falls short to restore the required data, then you need to recover the data by using advanced access recovery application.

As a practical scenario, you encounter the below error message when you attempt to mount a database:

"The Microsoft Jet Database engine could not find the object 'MSysACEs'. Make sure the object exists and that you spell its name and path name correctly."

After the above error message appears, the data saved in the database becomes inaccessible. In addition, you encounter the same error message each time you attempt to mount your system.

Cause:

As stated in the above error message, the Microsoft Jet Database engine is unable to find the 'MSysACEs' object. The object is either missing or corrupted.

Resolution:

To resolve the above error message and access the data saved in the database, you need to follow these steps:

 Create a new Access database and import all the database components into the new one.
 If the problem persists, use an inbuilt repair utility named "Compact and Repair."

In most cases, the inbuilt utility resolves your problem and the data becomes accessible. But, if the utility is unable to resolve your issue, then you will need to recover the data by using advanced Access Recovery application. These access repair applications employ advanced scanning algorithms to completely scan and repair the corrupted database. With highly graphical user-interface, these applications are easy to understand and implement. These applications repair and restore the corrupted database in its original format without modifying the contents of the database.
