Excel Crashing: Faulting module name: mso20win32client.dll

Anonymous

Hello,

I have constant crashes for Excel. It all started suddenly and it happens on two different computers (one a PC the other a laptop).

I have tried quick repair, online repair, uninstalling completely using the diagcab tool. Nothing works. The crash appears when doing simple tasks such as editing a chart, scrolling or selecting a cell. It happens in various files. I have also disabled all add-ins and it still happens. Below the error:

Faulting application name: EXCEL.EXE, version: 16.0.11029.20108, time stamp: 0x5c0b39a9

Faulting module name: mso20win32client.dll, version: 0.0.0.0, time stamp: 0x5c099da4

Exception code: 0x012a168b

Fault offset: 0x00000000001ea7b3

Faulting process id: 0x5a98

Faulting application start time: 0x01d492335c963195

Faulting application path: C:\Program Files\Microsoft Office\Root\Office16\EXCEL.EXE

Faulting module path: C:\Program Files\Common Files\Microsoft Shared\Office16\mso20win32client.dll

Hi All,

Thanks for all the provided information, your time and efforts during these days. We'd like to share a summary for the issue here which will benefit other community members.

Symptoms:

Office 365 for Windows apps crash frequently when we do any simple actions such as editing, scrolling or selecting a cell. The crash log in the Event Viewer shows faulting module name: mso20win32client.dll.

Workaround:

Run as administrator when you launch the apps.

Assessment:

This issue is caused by Sticky Password, the 3^rd^ party conflict. Please place Excel in ''ignoring programs' within Sticky Password settings. You can get further help from Lamantine Software to see whether they will update a fix.

Regards,

Rena

Update

I received a reply to my post about this Excel crash in the Excel/Windows 10/Office 2016 forum (same thread title as this one). The poster suggested that Sticky Password (SP) may be causing a conflict that crashes Excel. I made the necessary settings change to SP - making an entry for Excel.exe in the 'Ignored Apps' section. After testing this change, removing it and then reapplying it, I can confirm that Excel no longer crashes for me when running Excel as normal (i.e. not as Administrator). However, on this forum I doubt many of you will be running SP, but it may indicate another 3rd party program may be involved. I had been running SP for quite some time and it had never caused an issue with Excel, or any other program I run, so I'm not sure what started these crashes towards the beginning of December. I'm raising this issue with Lamantine Software, producers of SP, hoping they may be able to see why a conflict appears to exist.

Further update

As promised, I have had a response from Lamantine Software who publish Sticky Password. I have posted their reply here and it includes the steps previously outlined to resolve the immediate issue with the Excel crashes.

Quote:

We are sorry for this problem, our developers are already working on it. Possibly some other apps may cause similar conflicts but we recently found a conflict with our app. To resolve it immediately, please do the following:

1) Please navigate to the main Sticky Password window - Menu - Settings - Ignored apps and try to add the executive file of Excel to the list.

2) If it won´t help directly, on the same tab in the main Sticky Password window - Menu - Settings - Ignored apps, try to disable autofill for the 32bit or the 64bit apps accordingly to the version of the problematic app.

Thank you for understanding.

End quote.

Hopefully it won't be long before a permanent fix is supplied.

Hi All,

If the registry settings can’t fix the issue, we would like to collect the information below for further investigation:

1.      It seems all of you are using the 16.0.11029.20108. Does the issue happen to other users in your company? If so, are all the affected computers using this same version?

2.      When did the issue first happen? Was there anything changed before that? Some customers mentioned in another thread that the issue happened after Windows update? It seems 1 customer upgrade to the 18305 Windows insider version then fix the issue. To check whether this is the cause, please tell us your OS version. For example, 1809 (17763.194).

4.      Does the issue only happen to Excel app?

5.      Please provide us the whole crash log for further investigation. To collect it, you can provide them in the private message I have sent you. Please right click and save selected events to .evtx file so we can see the entire log by our side.

Thanks,

Rena
