What are uldsmpeg.ax Error Messages?

Dynamic Link Library uldsmpeg.ax Errors

uldsmpeg.ax is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like uldsmpeg.ax, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. Corel VideoStudio Pro) could share the same uldsmpeg.ax 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 AX 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 uldsmpeg.ax is attempted to be loaded either when Corel VideoStudio Pro is starting up, or in some cases already running. Some of the most common uldsmpeg.ax errors include:

Access Violation at address - uldsmpeg.ax.
uldsmpeg.ax could not be found.
Cannot find C:\Program Files\Corel\Corel VideoStudio 2019\Common Files\MPEG\uldsmpeg.ax.
Cannot register uldsmpeg.ax.
Cannot start Corel VideoStudio Pro. A required component is missing: uldsmpeg.ax. Please install Corel VideoStudio Pro again.
Failed to load uldsmpeg.ax.
The application has failed to start because uldsmpeg.ax was not found.
The file uldsmpeg.ax is missing or corrupt.
This application failed to start because uldsmpeg.ax was not found. Re-installing the application may fix this problem.

Your uldsmpeg.ax file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Corel VideoStudio Pro), or deleted by a malware infection. Furthermore, uldsmpeg.ax file corruption could be caused from a power outage when loading Corel VideoStudio Pro, system crash while loading uldsmpeg.ax, 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 uldsmpeg.ax 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 uldsmpeg.ax 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):

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

If the Step 1 fails to resolve the uldsmpeg.ax error, please proceed to the Step 2 below.

Step 2: If recently installed Corel VideoStudio Pro (or related software), uninstall then try reinstalling Corel VideoStudio Pro software.

You can uninstall Corel VideoStudio Pro software by following these instructions (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
In the search box, type "Uninstall" and press "ENTER".
In the search results, find and click "Add or Remove Programs"
Find the entry for Corel VideoStudio Pro 2019 and click "Uninstall"

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 uldsmpeg.ax error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

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

If Windows Update failed to resolve the uldsmpeg.ax 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 uldsmpeg.ax 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 uldsmpeg.ax file version. We maintain a comprehensive database of 100% malware-free uldsmpeg.ax files for every applicable version of Corel VideoStudio Pro.

Copy this file to the appropriate Corel VideoStudio Pro folder location:

Windows 10: C:\Program Files\Corel\Corel VideoStudio 2019\Common Files\MPEG\
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.

Download uldsmpeg.ax Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying uldsmpeg.ax to your appropriate Windows system directory. Corel typically does not release Corel VideoStudio Pro AX 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 uldsmpeg.ax and all other AX files for Corel VideoStudio Pro. An incorrectly installed AX file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
