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

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 Rena,

Thank you for your answer. You are a life saver! This bug had been bugging me for months. I have tried everything I can find on internet but nothing really worked.

I hope this time it's gone for good.

Cheers,

Chuan

Another update

Aad de Graaf posted a reply in the Excel/Windows 10/Office 2016 forum with regard an update to the Sticky Password (SP) program. Personally, I don't see this update available - certainly not via the Help/Check for updates option. He states that this SP update now has the Excel.exe coded internally as being ignored, so you can't add it manually to the ignored list anymore. Further, Excel is now crashing again (for him) and the only way to stop this is to terminate SP.

I have also (belatedly) found that SP is the cause of Visual Studio 2017 (VS) outputting numerous exception messages when running in debug mode. Neither VS or my program is crashing, but the generation of these messages has been annoying. I had added devenv.exe to the ignored list, but this didn't change anything, so I looked elsewhere for a resolution. However, today I found it by actually terminating SP. Low and behold, the messages have gone away!

I am now seriously thinking of ditching SP for my previous password manager, RoboForm. From what Aad de Graaf has said, I don't think I'd want to install the SP update (if you can get it) at this time, as it seems to bring back the original issue of this thread. I will also e-mail Lamantine Software again.
