Hello Gail,

Thanks for reaching out.

I'm sorry to hear that you're having trouble with the library 87 failed error. If you still get this issue after doing what was mentioned, you can try this.

If system files are broken, they can cause LoadLibrary issues without you knowing it. A fast repair can help a lot. As an administrator, open Command Prompt and type sfc /scannow to scan and correct common problems with your system. After that, execute dism /online /cleanup-image /restorehealth to correct Windows parts that are broken beyond what SFC can cure. It's typical for both tools to work in the background and take some time. When they're done, restart your computer to see if the problem is fixed.

let me know how it goes, and if you have any questions, please leave a comment below.

Thank you,

Randy, this answer is better than QA Assist which is for technicians not users. However, it would be good to know how long these tools will take typically in the background. Minutes, hours ? So far Microsoft have soent 1.5hours to tell me that it is an app problem and not Windows 11. The app experts say the reverse. What a surprise !

Randy, specifically, the error message I get is "Loadlibray failed with error 87. The parameter is incorrect". All Windows, Office, app and driv er updates have been done, as well as manyy system restores etc. This problem ONLY started with 1 app, Sibelius Ultimate, on 26th January after my Windows 11 update on the previous day. I have never experienced these problems before for over 20 years.

The "LoadLibrary 87 failed" error typically indicates an issue with loading a dynamic link library (DLL) due to incorrect parameters or access issues. Here are some steps you can take to remedy this error:

Check for Corrupted or Missing DLLs: Ensure that the DLL file that is failing to load is present in the expected directory and is not corrupted. If it is missing, you may need to reinstall the application that requires it.
Grant Access Rights: Make sure that the process token has the necessary access rights to load the DLL. This can be particularly relevant in Windows 10 and later versions where access rights are more strictly enforced.
Reinstall the Application: If the problem persists, consider uninstalling and then reinstalling the application that is generating the error. This can help ensure that all necessary files are correctly installed.
Run as Administrator: Try running Microsoft Edge as an administrator to see if that resolves the issue.
Check for Windows Updates: Ensure that your Windows operating system is up to date, as updates may fix underlying issues that could be causing the error.

If these steps do not resolve the issue, you may want to consult additional resources or support for further assistance.
