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:
[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

Have you gone back to your original Windows os? It worked for me so I will wait until they fix it to upgrade again. Everyday I get a pop up message telling me to upgrade for free. I have a year from July 29 to upgrade free
I have the same problem with my Office Suite bought through my employer's plan. I cannot seem to find any help whatsoever.
Hey Gaby, sorry the troubleshooter ran into an issue. I noticed that the dialog's buttons are in Spanish. Are you running the Spanish version of Windows where the Program Files folder is generally under "Archivos de programa" or "Archivos de programa (x86)"? We use environment variables, such as %programfiles%, but perhaps Office was also installed in a non-default location. I'll work with the team that authored the troubleshooter, so any details will help.
I posted my experience on Facebook with a warning not to upgrade.
Your response, "We are actively working on a fix to resolve this issue" doesn't cut it and the solutions that you suggested are not working either. Another example of very poor customer service.
