Cannot open some Office files after upgrading from Windows 7 to Windows 10

Anonymous

Hi everyone,

This is Bryan from the Office team. We are extremely sorry to learn that some of you are running into an issue with Office after upgrading from Windows 7 to Windows 10 where some of your Word, Excel and PowerPoint documents are failing to open with various error messages, such as:

Word: “Word experienced an error trying to open the file”
Excel: “This file is corrupt and cannot be opened”
PowerPoint:
- “The application was unable to start correctly"
- “PowerPoint found a problem with <filename>"
- “Sorry, PowerPoint can’t read <filename>"

[UPDATE - 8/25/2015]

On Monday, a fix went out to all Office 2013 Click-to-Run users that fixed the Protected View issue that was preventing some files from opening. For those users, the Office applications would launch and even creating new documents worked fine; however, opening some files resulted in various error messages like above. If you haven't already been prompted to install the August update, you can manually trigger by going into an Office application like Word, then select File > Account > Update Options > Update Now.

There are other known issues that could also cause similar error messages, but those are not related to the specific Protected View issue. Teams are working hard to determine the root cause and resolve those issues. For instance, if you are running Windows 10 and Office is running in Windows compatibility mode for a prior version, you likely will also experience issues.

We apologize for the inconvenience caused due to this issue!

Sincerely,

Bryan

I uninstalled and reinstalled Office twice while I was running 10 and the first time it worked better but often my files would open as "read only" and when I tried to save them I got a message that I needed permission. The 2nd time I reinstalled word it wasn't any better so that is what made me decide to go back to Win 8.1

However, I have talked to two people who LOVE Windows 10 but neither of them are big users of Office programs. Windows 10 worked okay for me if I didn't want to use Word or Excel but it seemed rather slow and now 8.1 seems so fast in comparison. I don't know if it is because I save my files to One Drive because if I managed to save a file it showed that it was on my C drive in Sky Drive. Go figure?

Has anyone noticed that there hasn't been a post from a Microsoft representative here for several days? Where do you suppose they are? Probably hiding and hoping the problem will just go away? C'mon Microsoft, it's time go get this mess FIXED!

Regarding compatibility between Win10 and MS Office 2010:
- as none of the suggested fixes or repairs have worked and I was still losing Excel files, today I rolled-back to Windows 8.1 using the Settings > Recovery feature.
I am looking forward to reinstalling the Windows 10 upgrade if and when the compability problem with MS Office 2010 is fixed.

Please notify me through this forum when the issue is resolved, and I'd be happy to try again.

Thanks,

Roxanne
