Microsoft Office 2013 Has Stopped Working

It's installed with most Epson Printers\Scanners.

I want to add my resolution to the list.

After installing Office 365 for Business on a PC, all the applications crash when started (even during the install I get a crash on the splash screen).  In the event log I find error 0xC0000005 with faulting module path "unknown."  The problem seems to be related to activation.  You can start the office products in safe mode but they are not activated.  Once you try to activate the software crashes.

I spent many hours on this problem including 3 hours on the phone with Microsoft support.  To their credit, the two techs I worked with really seemed to know what they were doing - despite all the things they tried it did not fix the problem. 

I tried absolutely everything to narrow it down.  In other posts I read people having the same issues and even after completely reloading their systems they still had the problem.  I found this hard to believe.   So, I decided to wipe and reload. Low and behold, the exact same problem occurred immediately.

Now, the solution I am going to give sounds preposterous and that is why I spent about 8 hours trying to eliminate every other possibility before doing something so basic.  After the reload it became apparent there must be a driver or hardware issue.  But, I eliminated all that too.

The solution that resolved the issue:

Reset the system BIOS - More specifically, I went into the BIOS setup and chose to Load Optimized Defaults.  I then tweaked a couple of settings back to where they needed to be and rebooted.

Office immediately began working properly.

Now, you must be careful with this advice. If you are not comfortable with it, please know that resetting the BIOS and then not understanding some of the options can leave your system unbootable.   Specifically, you need to make sure the SATA modes are changed back to their original setting after the reset.  Now, I compared the options in the BIOS before the reset and after the reset.  I could not find any option that I felt would be related to this issue, and the ones I tested would not cause the problem to reappear.

I don't know why this is a solution.  But, it raises questions about why the activation process in Office fails due to some kind of BIOS issue while every other application on the system works fine.

I had the same exact problem with my Office 365 Plus on Windows 8.1.  My issue turned out to be the drivers for my third monitor which is a StarTech.com provided product.  Exact model is a Trigger II part number USB2DVIE3 when searching it in startech.com website.  

The drivers provided were in the CD and they have updated drivers on their website here (this link will go directly to the driver download for you) - http://sgcdn.startech.com/005329/media/sets/Trigger\_Series\_Drivers/Trigger.zip

Or just visit the website and download it here: http://www.startech.com/AV/USB-Video-Adapters/USB-to-DVI-Multi-Monitor-Adapter~USB2DVIE3#dnlds

So, in summary, third monitor USB to DVI adapter from startech.com.

Hope this helps.

I get the error message that the program has stopped working for every app under Office.  I even get the message during installation of Office.  While Office is getting things ready and as soon as the welcome screen pops up I get the error but the app still installs in the background.  I have tried re-installing 4 times and get the same every time.  It does not work in safe mode either.  I'm running Windows 8.1 64-bit.
