What are Algo21.dat Error Messages?


Dynamic Link Library Algo21.dat Errors

Algo21.dat is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like Algo21.dat, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like mrt.exe - to follow. These files were created so that multiple programs (eg. FL Studio) could share the same Algo21.dat file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DAT file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when Algo21.dat is attempted to be loaded either when FL Studio is starting up, or in some cases already running. Some of the most common Algo21.dat errors include:

Your Algo21.dat file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with FL Studio), or deleted by a malware infection. Furthermore, Algo21.dat file corruption could be caused from a power outage when loading FL Studio, system crash while loading Algo21.dat, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix Algo21.dat Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your Algo21.dat issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the Algo21.dat error, please proceed to the Step 2 below.

Step 2: If recently installed FL Studio (or related software), uninstall then try reinstalling FL Studio software.

You can uninstall FL Studio software by following these instructions (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "Uninstall" and press "ENTER".
  3. In the search results, find and click "Add or Remove Programs"
  4. Find the entry for FL Studio 20.5.1.1193 and click "Uninstall"
  5. Follow the prompts for uninstallation.

After the software has been fully uninstalled, restart your PC and reinstall FL Studio software.

If this Step 2 fails as well, please proceed to the Step 3 below.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many Algo21.dat error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the Algo21.dat error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your Algo21.dat File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate Algo21.dat file version. We maintain a comprehensive database of 100% malware-free Algo21.dat files for every applicable version of FL Studio. Please follow the steps below to download and properly replace you file:

  1. Locate your Windows operating system version in the list of below "Download Algo21.dat Files".
  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate FL Studio folder location:
    Windows 10: C:\Program Files (x86)\Image-Line\FL Studio 20\Plugins\Fruity\Generators\Sytrus\Data\DX7Algos\
  4. Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.


GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve Algo21.dat 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 Algo21.dat Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying Algo21.dat to your appropriate Windows system directory. Image-Line typically does not release FL Studio DAT 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 Algo21.dat and all other DAT files for FL Studio. An incorrectly installed DAT file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
