What are ulvdmp4.ax Error Messages?


Dynamic Link Library ulvdmp4.ax Errors

ulvdmp4.ax is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like ulvdmp4.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 ulvdmp4.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 ulvdmp4.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 ulvdmp4.ax errors include:

Your ulvdmp4.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, ulvdmp4.ax file corruption could be caused from a power outage when loading Corel VideoStudio Pro, system crash while loading ulvdmp4.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 ulvdmp4.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 ulvdmp4.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):

  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 ulvdmp4.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):

  1. Hit the Windows Start button

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 ulvdmp4.ax 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 ulvdmp4.ax error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

Download ulvdmp4.ax Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying ulvdmp4.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 ulvdmp4.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.
