Excel.EXE-Application Error - 0xc0000142

Hi Msp2uga,

Thank you for your message in this forum. We understand the inconvenience caused and apologize for it. And we will try our best to help you.

According to your description, it seems that you encountered an error message when you used your Excel file.

If my understanding is right, generally, the error 0xc0000142 can happen if some Office program components have gotten corrupted. So we’d give you some suggestions below and hope that will help you:

1. We’d suggest you go to Control Panel > Programs > Programs and Features > select Project > right-click and select Change > Online repair.
2. You can also open your Excel in safe mode to check if the same problem will occur. It will help in identifying an add-in or extension that may be causing a problem on startup. As steps shown below: Right-click the Start button (lower-left corner) in Windows, and click Run.> In the Run box, type one of the command: excel /safe

If the suggestions above don’t work, to better understand your situation, could you provide the information below?

1. Could you provide the Product Information and version of your Office? Since you cannot open Excel, you can go to Word > File > Account and provide the full screenshot of it.
2. Do all Excel files have the same problem? You can try opening Excel directly to check if the same problem will occur.
3. Could you provide the screenshot of error message?
4. Do the other Office applications have the same problem?

Best Regards,

I had this happen to me yesterday as well, and so did a coworker. I tried running the quick repair on Office and it had the same results as trying to open a file. Then I tried the Online Repair and it essentially just uninstalled all the applications and then nothing else. After I gave up on it re-installing them, I manually did it myself and now they seem to be OK again.

I'm wondering if this is some sort of glitch in a background update for Office 365 that happened yesterday.

At the same time, for your concern about if this is some sort of glitch in a background update for Office 365 that happened, as far as we know, it seems that there is no such event happened.

Thank you for your understanding!

I am facing similar issue, still not able to get my excel up andrunning. It shows windows is searching for EXCEL.EXE.  In my program files>> Microsoft office>> Root>> EXCEL.EXE application has gone missing.

I have already tried re-installing, and online repair. None of them worked for me.

Hi shakshijajoo1,

Recently using my Excel spreadsheet and an update popped up.  The Error Code showing is 0xc0000142, Excel.EXE-Application error.  The application was unable to start correctly.  Why?
