Re: mso20win32client.dll

I dont have a solution. Here are my troubleshooting steps I have taken thus far:
-Uninstall/Reinstall P3Dv5
-uninstall/reinstall airport addon (airdrome at which crash starting time appeared)
-Uninstall/Reinstall aircraft addon (aircraft that was utilized when crash happened)
-uninstall/reinstall Windows Function Home & Pupil 2019
-re-registered all DLL'southward
-conducted sfc/scannow (no corrupted files constitute)
-conducted live update of Microsoft Abode Office & Student 2019 (this resulted in all role products being Uninstaller and P3Dv5 non loading to main carte du jour)
-Removed Microsoft Home & Pupil 2019
-Installed Microsoft Office 365
-Conducted live update of Microsoft Function 365 (result all Microsoft Office products Uninstalled and P3Dv5 not loading to main menu)
-conducted alive update of Windows OS
-wearied Microsoft tech back up
-contacted Lockheed Martin P3Dv5 tech back up
-rolled back windows update

All of these troubleshooting techniques have failed to isolate the root crusade of DLL. Furthermore, the file path to the mistake module yield no DLL at that place.
What is perhaps the most perplexing is that P3Dv5 is attempting to pull data from a DLL that doesn't exist.

I have so many questions I dont know where to brainstorm.

I don't know whether the steps set out below will solve your DLL problems simply I stumbled over your forum when trying to notice a solution for mso20win32client.dll issues that have suddenly emerged on a program called NeoPro, following a recent Part 365 update. I was able to solve my problem by reverting to an earlier version of Part 365 and so keeping Automatic Updates turned off.

To solve my issue for Neo Pro, I used the instructions at https://support.microsoft.com/en-ie/hel ... -2016-clic to install a specific version of Outlook that doesn't fail.
i. You'll need to know which marketing/update aqueduct you are subscribed to. Discover this within Outlook at File > Office Business relationship > Almost Outlook
ii. For my Dell OptiPlex (64-scrap Outlook) which is on the Monthly Enterprise Channel, Outlook Version 2010 (build 13328.20478 Click-to-Run) from December 8, 2020 works fine for NeoPro. Information technology's the latest available for that Channel.
3. For my Dell XPS13 (32-bit Outlook) and for the Toshiba laptop (64-flake Outlook), both on Current Channel, Outlook Version 2010 (build 13328.20408 Click-to-Run) from November 17, 2020 works fine for NeoPro. Microsoft'south Current Aqueduct release from Dec eight, 2020 (13426.20332) fails, equally does Current Channel, Version 2011 (build 13426.20404) from December 21, 2020.

Hope this may help someone.

Thanks for your answer. I have taken a look at the build of Office 365 I have (13426.20404 Click -to-run). I volition troubleshoot today to encounter if version 13228.20478 works.

I don't think substituting 13228.20478 for 13426.20404 will work, because the old is a Monthly Enterprise Channel version, while the latter is a Current Channel (i.e. retail customers). You can't switch channels. I'd be using 13328.20408 if I were you.
This link volition have you to a table which may aid (run into Version History halfway downward).

I tin can see from your post that you are on the nigh recent Current (previously known as Monthly) Aqueduct version of Function 365, version 2012, build 13530.20316, issued a few days ago. Refer Microsoft Version history at https://docs.microsoft.com/en-us/office ... ps-past-date

I suggest that the reason yous are all of a sudden receiving mso20win32client.dll errors is that your Office 365 automatically updated itself on its regular cycle, and therefore introduced to your automobile a bad version of Part 365. The fact that P3D won't run without Role 365 installed (as you lot report) implies there must be some interdependancy between P3D and Office 365, no affair how illogical that may be.

Based on my feel with another programme NeoPro which began reporting exactly these same errors and which I take at present resolved satisfactorily, my suggestion would be that you accept your version of Office 365 back to Current/Monthly Channel Version 2010 (build 13328.20408) from 17 Nov 2020, which doesn't have mso20win32client.dll issues, and then turn off Automatic Role 365 Updates.

Vaughan is right insomuch that an Role update introduced a CTD into another piece of software. It is therefore Microsoft'due south issue and then they need to be pressured into resolving.

Equally an FYI, I have done iii flights and spent several hours in the sim configuring FSUIPC since deleting the registry keys I recommended. My O365 is still latest build with automobile updates on.

Having the same issue. I removed the Lockheed Martin files from ProgramData and Appdata, which stopped the crashes. I then added everything back, crashes were back. Removed add together-ons.cfg and dll.xml in Appdata binder which has stopped crashes except for when I use PMDG aircraft, as far as I can tell. Not certain what to practice brusque of a reinstall.
