I also met the same problem. I sent 2 weeks ago AVAST all information and error codes without answer… >:(
Right now I have had to restore my computer with an older backup (Ghost) and I locked the Avast software update (libraries can be updated)
I have Program version 10.3.2225 and when I open Office 2013 I get the error
The application was unable to start correctly (0xc0000005). Click OK to close the application
I uninstalled and reinstalled Office, still the same issue. Uninstalled Avast (while Office still installed) and it opened fine. Very frustrating having to uninstall and reinstall Avast whenever I need to use Office.
Absolutely livid that 3 weeks, a new SSD and a Windows 10 license only to find that this is a known issue that has not been shared with end-users for a critical application!
Sure, mea culpa for not considering that this product might have been a root cause and actively searching these forums for solutions but I appear to be overly trusting?..
Anyway, I can confirm the exact same issues reported by everyone else…
Windows 7 and 10 64bit all act in exactly the same way. What confuses things is that you find yourself trying the myriad of other solutions for 2013 such as disabling graphics hardware acceleration, recreating profiles, etc… And some of them work briefly here and there, then they don’t…
Oh and disabling Avast does not resolve the issue as Avast is quietly continuing to block/break things despite being told not to. That’s an interesting “feature”
The suggestion to update to the beta seemed like a good idea but with all the other issues like Macrium reflect conflicts, etc… that seems a little counter intuitive… For now I’m back to Win defender and applying a lot of common sense when clicking anything.
In all seriousness, Avast staff… You need to be highlighting this as a known issue and letting your customer base know… Not waiting for more p*ssed off end-users to find out the hard way… Waiting 2-3 weeks with no notice except this forum post is just poor communication and won’t do your product rep’ any favours.
For now Avast is off my systems and I doubt I’ll be reinstalling without a bit note to test everything 15 times before I update my main systems.
To be fair, only some user had a conflict with Avast and Office 2013.
I was one of those that never had a problem. I didn’t need the update to solve any Office 2013 problem.
I can confirm there was a compatibility issue between Avast and Office 365 on 64-bit OSes. I couldn’t reproduce it on my own computer, but we got some memory dumps and we fixed this problem. (28/6/2015) – the fix is probably also included in Avast 2015 R4 Beta (https://forum.avast.com/index.php?topic=175753.0).
I have also been experiencing this issue and trying to troubleshoot the last several weeks. I’ve reinstalled office multiple times, disabled windows firewall and avast with no effect. Could this also be why my Adobe Creative Cloud apps can’t communicate with Quicktime? because that started about the same time too! They use TCP to work with Quicktime. I also submitted a support ticket.
Updated Avast 1 week ago to latest version as it was asking me to, a day later noticed that when I start PC Microsoft OneNote tells me its crashed.
Can’t open any Microsoft Office 2013 applications as they error and crash.
I had some success getting only 1 Office application to open, if I stopped all Avast services, I could open OneNote 2013 sometimes, but no other Office apps like Excel or Word.
I re-installed Office after removing it and no change, my PC is fresh installed a month ago and doesn’t have much else running.
Now I have Office2013 apps all working, but only as I uninstalled Avast. Shame as it was best anti-virus application I had used.
