Windows 10: Unable to open Word docs or PowerPoint slides

Every time I try to open slides through PowerPoint or Word document I get a message that says "Install failed. Please contact your software vendor".

PowerPoint file crashes PowerPoint upon opening

since this happens in some of the computers only, suggest that you open the file on working computer and copy everything and paste to a new powerpoint file.
most of the time it works to me. *Smile

 

Unable to open PDF or Word docs

I'm suddenly unable to open pdf or word docs that are posted on a website that I access regularly. No error message. Just clocking and then a blank screen?

 

Unable to open attachment (Word files) since I upgraded to windows 10

Since upgrading to Windows 10 I am unable to to preview Word Documents in my Outlook 2013. I am also unable to open Word Documents that have been emailed to me. This is something new that was not a problem prior to the upgrade.

• The error for the preview says: This file cannot be previewed because there is no previewer installed for it.
• Then when I go to open the Word Doc it says: Word experienced an error trying to open this file.
  

Its not one document it is all Word documents that are sent to me. Documents that I was able to preview before and open before that are sitting in my Outlook I am unable to open now.

I need to fix this asap. Your help would be greatly appreciated.

Word - Options - Trust Center - Trust Center Settings... - Protected View - uncheck Enable Protected View for Outlook attachments. Once done I was able to double-click the Word attachment in Outlook.
