SQLite is one of the most widely deployed database engines on the internet today, and it is being used by several programs. Adobe uses SQLite for Photoshop Lightroom, Adobe Integrated Runtime (AIR) and Acrobat Reader. Apple also used SQLite for most of its native applications running on macOS and iOS devices. Dropbox, Facebook, Android, Chrome, Intuit, McAfee, Microsoft, Firefox, Python, Skype, PHP, and Tcl/Tk programming language all use SQLite in one form or another.
All these pieces of software that use SQLite needs the sqlite3.dll for the programs to run smoothly. Any damage or corruption that happens to the sqlite3.dll file can cause errors and prevent the associated program from functioning properly.
What is SQLite3.DLL?
SQLite3.DLL is the dynamic-link library file containing the command-line tools used for managing the SQLite database. When you install an app that uses the SQLite database, the SQLite3.DLL is also automatically installed on your computer.
What does SQLite3.DLL do? Just like .exe files, DLL contains commands and instructions the operating system can use on how to perform specific tasks involving multiple SQLite-related applications. But unlike executable files, DLL files, like SQLite3.DLL, cannot be launched directly so it needs to be initiated by another code that is already on the system.
Pro Tip: Run a dedicated PC optimization tool to get rid of incorrect settings, junk files, harmful apps, and security threats that can cause system issues or slow performance.
Is SQLite3.DLL a Virus?
In most cases, SQLite3.DLL is considered a legitimate file since it is associated with various applications that rely on the SQLite database. If you recently installed an app, such as Adobe or Skype, then it is normal to find SQLite3.DLL on your computer.
However, if you don’t have an SQLite-related app on your computer and you see this DLL file or you come across an SQLite3.DLL error, then it might mean that you have a malware on your computer disguising itself as SQLite3.DLL.
You should also consider other symptoms that your computer is experiencing. For example, does your computer seem more sluggish than usual after you’ve noticed the presence of the SQLite3.DLL? Do you see more ads constantly being delivered by your browser or the apps you are using? Are there other suspicious apps that suddenly appeared on your computer and you can’t remember installing them? Do you seem to always lack RAM, CPU, and storage space because something else is hogging your resources? If you don’t see anything else that you could attribute these suspicious activities to, then you most likely have malware on your computer. However, this does not automatically mean that the SQLite3.DLL file is the virus.
One of the most common errors that Windows users encounter is missing or not found sqlite3.dll issues. The error message can be any of these versions:
- Sqlite3.dll Not Found
- This application failed to start because sqlite3.dll was not found. Re-installing the application may fix this problem.
- Cannot find [PATH]\sqlite3.dll
- The file sqlite3.dll is missing.
- Cannot start [APPLICATION]. A required component is missing: sqlite3.dll. Please install [APPLICATION] again.
- The program can’t start because Sqlite3.dll is missing from your computer
- The procedure entry point sqlite3_wal_checkpoint could not be located in the dynamic link library Sqlite3.dll
- None of the dynamic libraries can be found: Sqlite3.dll
This error can happen when your computer suddenly shuts down when you are running or installing a program that uses an SQLite database. It could also appear when you are installing a Windows update since Microsoft also uses SQLite on Windows 10 apps. This error is so persistent and causes great annoyance to Windows users because it keeps popping up out of nowhere all the time.
This sqlite3.dll error is caused by events that lead to the deletion or corruption of the sqlite3.dll file. For example, a registry glitch, hardware failure, software incompatibility, and even malware infection can cause a sqlite3.dll error.

How to Fix SQLite3.DLL Errors
If you get the SQLite3.DLL is not found error all of a sudden, don’t download the DLL file from DLL download sites to fix the issue.

If the error appeared right after you installed an app or a system update, you can roll back your device to its last known good configuration. In other words, you can roll it back to the time when it was working without the error.
- Download the sqlite3.dll from the SQLite.org website. Usually, it is not recommended to download files from other sources because it might be more dangerous. However, we can make the exception this time because SQLite.org is the original source of the SQLite.DLL file so it is safe to download.
