Outlook 2013 in Windows 7 Pro is not loading

I’ve seen this issue come up in the Forum and be resolved with Windows 8.1, but I use Windows 7 Pro. Outlook 2013 does not load on my PC. I use avast! Pro. When I try to load Outlook, the loading screen shows that it is loading the avast! Add-in, but then I get the error message that OUtlook has stopped working. I disconnected avast! and restarted the PC, but that didn’t work. I can’t open Outlook to disable the add-in. I use Office 365 and I’m able to get to Outlook through the Web App, but that is very cumbersome. I am also able to access my Outlook account on my mobile devices which do not have avast!

Any ideas on how to fix Outlook on my PC?

Thank you.

Disable mail checking in avast and let us know if Outlook is working without it.

Thank you. I turned off the mail shield and restarted the computer. I have the same problem.

Ok, problem not solved but at least we ruled out a possible cause.

Now try this:

The first step in that answer is “Open Outlook”. The problem is I can’t open Outlook at all on my PC. I can do so on my iPad and iPhone, but that’s just the web app from Office 365. I appreciate you taking the time to help.

Open Outlook in Safe Mode (http://www.msoutlook.info/question/270)…then go disable Avast Plugin.

Of course a clean uninstall and re-install of Avast may solve since you will ultimately want the Avast Plugin…but the above will confirm something is mucked-up in the Add-In.

Avast Clean Un- & Re-Install

  1. Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition.
    Avastclear : http://files.avast.com/iavs9x/avastclear.exe
    Rejzors Uninstall tool: http://rejzor.wordpress.com/avast-cleanup-tool/

Here are the Avast installer links. Note: You need to be ONLINE during this install.

4. Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn’t) - reboot.

If there is anything related to Avast with a yellow triangle then uninstall it (highlight, right click) and reboot.

Thank you. Re-installing Avast seemed to do the trick.
