mso20win32client.dll

[86SWONAVY]

P3D,

Greetings.

I am having a CTD with the following fault module path and I am having difficulty isolating the root cause. My hope is to see f there is a troubleshooting technique to avoid having to conduct a complete OS reinstall. I'm curious how Microsoft Office and P3Dv5 are connected in any way? Fault troubleshooting has directed the issue to Microsoft Office, however, I am confused about how P3DV5 and Microsoft Office are connected. I am running the latest Windows install, and Microsoft Office version 18.2008.12711.0

Any assistance would be greatly appreciated. Please let me know if you require anything further.

I started experiencing this error after I ran Windows Update a couple of weeks ago. I fixed the problem by going to Add or remove programs, select Modify for the office program and run Repair.

Best regards,

I also was getting this error after an MS Office update got installed last week. I just uninstalled office from my simming machine, and the CTDs have cleared up.

I have MS 365 Personal, no problem to report.

Is your MS Office an older version?

I also have MS 365 Personal, and I get the mso20win32client.dll error intermittently.

Nope, using the most recent MS365. Everything worked great until a Office "Security Update" got installed on the 20th of December. I rolled back the update initially, and the CTDs went away, but the incessant forced MS updates kept reinstalling the update every evening, and the CTDs kept coming back. I just went ahead and uninstalled MS 365 completely and no problem since. I don't need office on my simming computer. I guess the big question is, why is a flight simulator linking Office libraries in the fist place?

How can I tell if I have the problem MS365 Personal update installed?

ALCON,

Thank you for the feedback as I'm not alone in having this issue. I too question why P3D is pulling or communicating with Microsoft Office in the first place. I find that odd.

Here are my troubleshooting efforts thus far:

-Reinstall P3DV5 (no effect)
-Uninstall Microsoft Office (P3D does not load menu. P3Dv5 still in task menu, but will not load)
-Reinstall Microsoft Office (CTD intermittent)
-Registered DLL files via CMD Prompt (issue not resolved)
-Installed OutByte PC Repair (No effect)

I'm contemplating a complete OS reinstall but I don't see how that will fix a DLL issue.

Louis,

Thank you for the tip. I completed that troubleshooting advice however the root cause has yet to be isolated.

Office version installed is 16.0.13426.20404

[Martyson]

My Office version : Version : 18.2008.12711.0
No problems.

[86SWONAVY]

My Office version : Version : 18.2008.12711.0
No problems.

This appears, the issue at hand that is, to be an Office Problem. Now my understanding is that Microsoft Office is a stand alone program, not subject to updates. That understanding, if I uninstall and do without Microsoft Office, P3D does not load. On the other hand, if I upgrade from Microsoft Office 2019, to say a newer version, 2020? Would that resolve the issue?
My thought process is that is another $150 expenditure just to resolve a DLL file?

And if it doesn't, I now have 2 versions of Office.

Additionally, the thought of purchasing Office 365 isn't appealing because that's a yearly subscription and I dont know if I can justify the monthly expenditure.

@ 86SWONAVY ,

My understanding from my Old Office (2010 I think it was?) version is that MS is no longer updating it (supporting it?).

I got the Office 365.

Maybe give Office Support a call or E-mail.

I must be completely misunderstanding the version of Office I have. I have Home &Student 2019 my thought process is that I have Office 2019. From what I read the latest Office updates are for Office 2010?
Again curious as to how this DLL is connected with P3dv5, and how to update Office to latest version.

Or do I have to subscribe to Office 365, which, at the current moment is NOT installed on my computer.

@ 86SWONAVY ,

You are ok with Office 2019 as far as I can tell.
Comes with Security updates but no Upgrades.

You paid $149 (US) for the software, correct?

I am not having that problem with MS 365.
