And it can happen at any time and with any Access version too, while opening/closing Access 2010 / 2013 files or while working with reports.
But why does it happen? Why does MS Access crash without notice even when everything worked absolutely fine the previous day?
The most common reasons for Access database crash include:
If you’ve been facing frequent crashes when working with MS Access, the actual cause for them might very well be one of the reasons mentioned above. To resolve the problem use one of the techniques mentioned in the next section.
Starting with the simplest of solutions, here’s all that you can try to fix/repair MS Access database files:
Try to stop your anti-virus program for the duration that you’re working with MS Access, especially reports, and see if it helps. You could also try disconnecting from the Internet for the entire duration that you work on Access database to avoid conflict scenarios. Once you’ve finished your work, remember to turn the anti-virus back on.
Try to decompile the database and then recompile it. You may use the following process for this:
After executing these steps, verify if the problem still exists.
Try to narrow down which report is causing the issue by studying the crash report or error log. Once you have, take a backup of the Access database file and then delete that report. Thereafter, creating a new empty database and import all the objects from the old one into it. Now recreate the report and check to see if the problem still exists.
Note: If the report in question is too complex to be rebuilt from scratch, you can also restore it from a previously saved backup copy.
If you’ve been experiencing the Access database crash while opening reports on a few machines only, you might be dealing with a low memory issue. Use a memory usage checker application during your regular working hours. If nothing else, this should help you establish that you’re not putting unnecessary load on your machines.
If the crashes are occurring in a single report on different computers and with different users, it might be due to corrupt binary data within the report. Remove binary from such reports as follows:
If your Access database contains images or other OLE object fields it can often give rise to troubles like Access keeps crashing while opening reports. If you need to store image data, then a better approach is to store the filename, and save the actual images to a standard location. Once you’ve done this, rebuild the entire database from scratch. This will take a lot of time and it is quite an exhausting approach but it just might give your database a fresh start.
If none of the above-mentioned techniques work or of you don’t have the time or resources to perform a full database rebuild, repairing the Access database using a competent automated application might be a good idea.
