What are db.opt Error Messages?


General db.opt Runtime Errors

db.opt file errors often occur during the startup phase of WampServer, but can also occur while the program is running. These types OPT errors are also known as “runtime errors” because they occur while WampServer is running. Here are some of the most common db.opt runtime errors:

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\wamp\bin\mariadb\mariadb10.4.10\data\test\db.opt

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.


Most OPT errors are due to missing or corrupt files. Your db.opt file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with WampServer), or deleted by a malware infection. Furthermore, db.opt file corruption could be caused from a power outage when loading WampServer, system crash while loading or saving db.opt, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.

If Windows Update failed to resolve the db.opt error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

  4. Restart your computer.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve db.opt problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.



Download db.opt Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying db.opt to your appropriate Windows system directory. Romain Bourdon typically does not release WampServer OPT files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing db.opt and all other OPT files for WampServer. An incorrectly installed OPT file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
