.NET Runtime version 4.0.30319.0 - There was a failure initializing profiling API attach infrastructure. This process will not allow a profiler to attach. HRESULT: 0x80004005

Hello,

I have been receiving this error for months and have not been able to identify a solution. This error occurs on Windows 11, but does not occur on one older Windows 10 machine.

This error occurs when I save (an actual local file write to disk) an empty or populated Word 2024 document.
It also occurs when I save an empty PowerPoint or populated document.
However, this error does not appear when saving an empty Excel spreadsheet or fully populated spreadsheet.

I have repaired MS Office multiple times using the quick and full online process.

I tried uninstalling and reinstalling, but the symptoms persist.

I tried deleting the normal document template and letting Word create a new template, but the problem persists.

If I create an empty Word document, add a small amount of content, and save it, the error occurs. The same error results when I make a small or large change to any document.
If I launch Word using "winword /safe" and create/save a blank document the error does not occur.
If I paste a large Word document into an empty Word file that was created in the safe mode, the error occurs when it is saved to disk.
However, if I make a slight modification in the Word file created in the last step and save it, no error occurs. Strange?!?!

We do not use cloud storage for any of our documents and do not allow auto save to MS cloud. All documents are all saved to a local machine disk drive and later backed up on our network. Critical backups are stored on non-volatile media.

MS cloud storage is disabled.

How can I track down the issue and resolve this problem that is filling up the event log with these errors?

Thanks,

Answer 1

The error you are encountering, "There was a failure initializing profiling API attach infrastructure. HRESULT: 0x80004005," typically indicates a problem with the .NET runtime or the Office installation on your Windows 11 machine. Since you mentioned that the issue does not occur on an older Windows 10 machine, it suggests that there may be compatibility or configuration issues specific to your Windows 11 setup.

Here are some steps you can take to troubleshoot and potentially resolve the issue:

Check for Windows Updates: Ensure that your Windows 11 installation is fully updated. Sometimes, updates can resolve underlying issues with the .NET framework or Office applications.
Reinstall .NET Framework: Since the error is related to the .NET runtime, consider uninstalling and reinstalling the .NET Framework. You can download the latest version from the Microsoft website.
Check for Conflicting Software: Sometimes, third-party software can interfere with Office applications. Check if there are any recently installed applications that might be causing conflicts and try disabling or uninstalling them.
Run Office in Safe Mode: Since you mentioned that running Word in safe mode does not produce the error, this indicates that an add-in or customization might be causing the issue. Try disabling all add-ins in Word and PowerPoint to see if that resolves the problem. You can do this by going to File > Options > Add-ins, and then manage COM Add-ins.
Create a New User Profile: Sometimes, user profiles can become corrupted. Try creating a new user profile on your Windows 11 machine and see if the issue persists when using Office applications under that profile.
Check Event Viewer: Since you mentioned that the event log is filling up with errors, check the Event Viewer for more specific error messages related to the issue. This can provide additional insight into what might be causing the problem.
Contact Microsoft Support: If none of the above steps resolve the issue, consider reaching out to Microsoft Support for further assistance. They may have more specific tools or insights to help diagnose the problem.

By following these steps, you should be able to narrow down the cause of the error and hopefully find a resolution.

Windows Updates: I have checked for windows updates many times and this error has persisted through multiple updates this year.

.Net Updates: I have reinstalled, uninstalled and reinstalled, and tried every repair option available.

No New Software Installed: I have not installed any new software other than MS Office 2024.

Word Safe Mode: Your AI response in NOT correct for the Safe Mode. Saving an empty Word document did not cause the error. However, saving a Word document in safe mode with content did cause the error. There are no enabled Add-Ins when I view them from:

File > Options > Add-ins

Event Viewer: The event ID is always 1022 with the same message as posted in this message. NO deviations whatsoever.

User Profile: I will check a new profile and report back.

Hello,

I created a new user profile before reinstalling Windows 11. I copied the original files to the new profile. In Outlook, I had to reenter about 16 email address passwords that were not copied to the new user profile. Other than that, I was able to run batch files, build VS applications, and access my data.

When I finally got everything working with the new profile, the error event still persists when saving documents.

I then reinstalled Windows 11, and the error event still persists when saving documents.

I had already deleted and rebuilt the search indexing several times over the past two days. However, I rebuilt the search indexing after the Windows 11 install as a precaution.

Usually, the event ID associated with this error message was already gone when I tried to find it in the Task Manager Details window. However, I finally identified the SearchFilterHost.exe file as the one that is actually causing the error when Word and PowerPoint documents are saved.

I finally disabled search indexing for all locations on my hard drive, which eliminated the event error 1022 that had been frequently occurring. I repeatedly opened, modified, and saved files without any event errors being displayed.

Once I re-enabled indexing for my file locations, these event errors began occurring. No other applications or files were being used during this time.

Thanks for your assistance.

The following may be another related error:

Event ID 10024 for the Windows Search Service has been suppressed 95 time(s) since 10:09:51 AM. This event is used to suppress Windows Search Service events that have occurred frequently within a short period of time. See Event ID 10024 for further details on this event.

Hello,

I have been able to recreate and document this error on all of our Windows 11 machines with the same OS version as given earlier. They are all Dell laptops. This issue is reproducible for all Users on each machine. I have also verified this event error issue for one laptop that still runs Windows 10.

I understand that SearchFilterHost.exe runs as a key part of the Windows Search service that indexes files and content for fast searching, but the current behavior of throwing numerous event error is not conducive to useful error logging.

As a developer, I use the event log frequently, which requires a lot more time these types of errors. I know that the event logger has a filter mechanism, but it is clunky to use and it hides a real issue.

Microsoft should consider adding the application name with its ID number. It would make debugging and tracking down error sources much easier. The SearchFilterHost.exe frequently removes itself from the Task Manager list before it ID can be viewed. Hence, the name of the executable should be added to these types of errors.

Thanks for your assistance.

Hello,

To temporarily eliminate many scores of event errors over a short period of time due to the activation of the SearchFilterHost.exe file, I disabled indexing for each folder that contains the most actively worked documents on my laptop. The issue with this temporary fix is that each machine and User profile must be individual tweaked. Ugh!

Hope Microsoft can come up with a permanent fix to eliminate this issue.

Thanks for your assistance.

I found a more optimal short term solution to eliminating this Event Error 1022.

I enable folders for file indexing using the Indexing Options from Control Panel.

I selected the folders that I wanted to disable file content indexing on, right clicked and removed the check on the "Allow files in ..." option.

I tested to verify that I could find all of my files in folders and sub-folders.

Hope this information saves time for others having this Event Error issue.

Let me know if I can be of any further assistance to Microsoft in solving this problem.
