Fix Corel VideoStudio Issues: Not Opening or Working on Windows 11

Step 1: Disable Windows Security

Windows Defender may sometimes treat Corel VideoStudio’s files as potential threats. Disabling it can resolve opening issues:

• Press Windows key + I to access the Settings menu, then go to Privacy & Security > Windows Security > Virus & threat protection.
• Click on Manage settings under the Virus & threat protection settings section.
• Toggle off the switch for Real-time protection.
• Restart your PC and attempt to launch Corel VideoStudio again.

Pro Tip: Consider re-enabling Windows Security after testing to keep your system protected.

Step 2: Rename the uvDV.dll File

The uvDV.dll file can sometimes lead to launch problems. Follow these steps to rename it:

• Open the Task Manager and end all Corel VideoStudio processes found under the Processes tab.
• Launch File Explorer by pressing Windows key + E, and navigate to C:\Program Files\Corel.
• Open the Corel VideoStudio folder, locate uvDV.dll, right-click it, and select Rename. Rename it to uvDV-old.dll.
• Test if Corel VideoStudio opens correctly now.

Pro Tip: Keep a backup of any newly renamed files in case you need to revert the changes.

Step 3: Recreate the Program Files

Renaming the program version folder can help reset application configurations:

• Ensure all VideoStudio processes are closed via the Task Manager.
• Open File Explorer and navigate to %AppData%\Ulead Systems\Corel VideoStudio Pro (x64).
• Right-click the folder and select Rename. Append _old to the folder name.
• Restart Corel VideoStudio to check if the issue is resolved.

Step 4: Repair Visual C++ Redistributables

To ensure proper functionality, Visual C++ Redistributables must be intact. Here’s how to repair them:

• Open the Run dialog by pressing Windows key + R, type appwiz.cpl, and hit OK.
• Find the Microsoft Visual C++ Redistributable entries, select each, and choose Change/repair.
• Click Repair and follow the onscreen prompts to complete.
• Launch Corel VideoStudio to verify if the issue persists.

Step 5: Update Visual C++ Redistributables

If the issue continues, ensure you have the latest version installed from the official Microsoft site.

Step 6: Repair or Reinstall Corel VideoStudio

If all else fails, you may need to perform a repair or a clean installation of VideoStudio:

• Open the Run dialog by pressing Windows key + R, type appwiz.cpl, and hit OK.
• Locate Corel VideoStudio, select it, and click Uninstall.
• You can first try Repair. If problems persist, opt for Remove and ensure to delete all associated app files.
