0x00002ef9 – Error_Sxs_Duplicate_Tlbid – Two or More Components Referenced Directly or Indirectly by the Application Manifest Have the Same COM Type Library TLBIDS

Error code 0x00002ef9, known as Error_Sxs_Duplicate_Tlbid, happens when an app has parts that share the same ID number for a type of library.

This mix-up can confuse the computer, causing the app to crash or not work right. It usually happens when there are different versions of the same part or when parts are listed more than once.

You might notice the app not loading properly or missing features. To fix it, check the app's details and make sure each part has a unique ID.

Understanding this error helps make apps run better and stay stable.

Error meaning:

The error "Error_Sxs_Duplicate_Tlbid" means that two or more parts in a program are using the same identifier.

This confuses the system, making it hard to know which part to use, leading to problems or crashes in the application.

Causes:

Potential reasons for the "Error_Sxs_Duplicate_Tlbid" on your system:

1. Multiple components in the application manifest have the same COM Type Library Identifier (TLBID).
2. Different versions of a component are included by mistake, causing conflicts.
3. There are duplicate references to components in different assemblies.
4. Configuration errors like wrong versions or missing entries.
5. Issues with third-party libraries that have overlapping TLBIDs.

Symptoms:

Symptoms of "Error_Sxs_Duplicate_Tlbid":

1. The software may not load correctly.
2. Users see error messages about missing parts.
3. The application might not start up properly.
4. Some features of the software may not work or seem strange.
5. The application could crash completely, stopping work.
6. Logs may show warnings about conflicting type IDs.
7. Important settings or files might not be configured right.

Solutions:

Step 1: Find the Problem

Look at the application manifest to find the parts that are causing the "Error_Sxs_Duplicate_Tlbid" issue.

These parts are trying to use the same COM Type Library TLBID.

Step 2: Use a Tool

Use the Fusion Log Viewer tool.

This tool will help you see where the problems are happening and why the application can't find the right files.

Step 3: Change the Manifest

Edit the application manifest.

Make sure that each part of the application has a different TLBID so they don't conflict with each other.

Step 4: Combine Components (if needed)

If you find that some components are the same and not needed, you can combine them into one.

This will help reduce confusion and errors.

Step 5: Review Assemblies

Check the related assemblies to see if they need to be updated.

Make sure they also have unique TLBIDs that match the new manifest changes.

Step 6: Test the Application

After making all these changes, run the application again.

Make sure to check if the error is gone and that everything works correctly.

Step 7: Keep it Stable

Impact:

• Causes application crashes and unexpected shutdowns.
• Prevents important features from loading properly.
• Makes the application unresponsive during important tasks.
• Wastes time and resources on troubleshooting instead of working on important things.
• Can lead to financial losses and hurt the company's reputation.
• Affects overall performance and efficiency of the system.

Relevance:

The error related to duplicate TLIDs can occur in Windows operating systems, especially in Windows 10 and Windows Server versions.

This error can also affect software applications like Microsoft Office and some database management systems. It can cause problems like making applications not work properly and can lead to issues with the data being used.

To fix this, it's important for organizations to manage their software carefully and follow good practices in software development. This helps to keep everything running smoothly and ensures that users have a good experience.

Prevention:

To avoid encountering the Error_Sxs_Duplicate_Tlbid in the future, follow these steps:

1. Keep a list of all software and their types.
2. Check this list regularly to find and fix any mistakes.
3. Make sure each software part has its own unique ID.
4. Use tools that can automatically check for problems in software lists.
5. Talk often with team members to make sure everyone is following the same rules.

What Is a COM Type Library Tlbid?

A COM Type Library TLBID is a special number that helps identify different sets of information about computer parts, called components. This number makes sure that programs can work together correctly and helps keep track of different versions of these components.

How Can I Check for Duplicate Tlbids?

To check for duplicate TLBIDs, look at the app's manifest file or the registry entries on your computer. You can also use special tools that help manage components, or use other software to find and fix any problems with TLBIDs.

Are There Tools to Help Fix This Error?

Yes, there are tools to help fix this error. Some useful ones are Visual Studio's Fusion Log Viewer and Microsoft's Sysinternals tools. These can help find and fix problems with components, especially with something called COM Type Library TLBIDs.

Can This Error Affect System Performance?

Yes, these errors can slow down your system. They can cause programs to clash, use more resources than needed, and even crash. To keep everything running smoothly, it's important to make sure all parts of the software work well together.

Is This Error Specific to Windows Operating Systems?

Yes, this error happens only on Windows computers. It comes from problems in the Component Object Model (COM). This is important for Windows and affects programs that need COM type libraries to work properly.
