2. 2. Run the System File Checker (SFC)
3. 3. Adjust permissions on the TypeLib registry key
4. 4. Disable third-party antivirus software

Solution 1: Copy the DLL file to the SysWow64 folder

This method has been known to work for people who receive error messages while trying to run files from the System32 folder. The error is caused by an OCX file or other files in the System32 folder. Thus, copying the said file to the SysWow64 folder and registering it again might fix the issue.

The process is quick and straightforward, and you'll be done in a few minutes. Here are the steps to follow:

Step 1. Open File Explorer and navigate to the System32 folder. You can do this by pressing Windows+E to open File Explorer.

Step 2. In the System32 folder, find and copy the file that is causing the error message. For this article, we'll use an OCX file as an example. Search for the OCX file in the System32 folder, then copy it once you've found it.

Step 3: Next, locate the SysWow64 folder on your system, open it, and paste the OCX file that you copied into this folder.

Step 4. Next, you will need to re-register the DLL file. Open a Command Prompt and run the DLL registration command; this should solve the problem if it was caused by a simple error in the file.

If this doesn't work for you and you're still getting the error, don't worry. You can try the other fixes below.

Fix 2: Run the System File Checker (SFC)

Sometimes, due to corrupted system files, you might encounter a failure in the DlldRegisterServer command prompt. Hence, checking and repairing the files can help resolve the issue.

Just follow these steps to run the SFC command.

Step 1: Type “Command Prompt” in the search box, and then click “Run as administrator” from the options.

Step 2. In the Administrator Command Prompt, type in sfc /scannow and press Enter. Wait for the scanning process to finish, which might take a few minutes.

Step 3: After the scan is complete, you can restart your system and check if the DllRegisterServer failed issue has been resolved.

If the problem is due to a corrupted file, this should fix it. If not, there may be other issues at play, and you can try the repair methods explained below.

Solution 3: Adjust permissions on the TypeLib registry key

If the problem is not with the file, it might be an issue with permissions on the TypeLib registry key. If you don't have enough permissions, you'll get a DllRegisterServer error. So, modifying the permissions might help resolve the issue.

Follow these steps to change the permissions:

Step 1. Press Windows+R to open the Run dialog box, type regedit, and press OK.

Step 2. In the left pane, expand the HKEY_CLASSES_ROOT option, scroll down to the TypeLib option, right-click it, and select Permissions from the drop-down menu.

Step 3. In the window that appears, select the user account and check the "Full control" option. Click the "OK" button, then click "Apply" to save the permissions settings.

After that, you can register the DLL file again without any errors.

However, if the problem persists, you can try the last resort.

Fix 4: Disable third-party antivirus software

Sometimes, the error might be due to the antivirus software that you use on your system. So, if none of the above solutions work, you can try disabling this antivirus to fix the error.

The steps to disable an antivirus program vary by product.

Step 1. Right-click on the third-party antivirus software's icon in the system tray.

Step 2. Choose an option from the drop-down menu to temporarily disable your antivirus.

Step 3: When you're done, click the “OK” button.

Try running the DllRegisterServer command prompt after this. It should work without displaying any error messages. When you're done, don't forget to re-enable your antivirus.

So, that's all the fixes to resolve the “DllRegisterServer was not found” error in your system. In most cases, one of these fixes should solve the problem, and you won't see the error message again.
