During upgrading of Avast 4->5, the Outlook plug-in is not upgraded for other user accounts on my machine.
I’ve WinXP SP3, Office 2003 SP3, multiple windows user accounts, each having his own Outlook Pop3 account.
I did the upgrade from an administrator account. For this user, the outlook plugin is correctly upgraded.
For all other users, it is not changed. When they start Outlook they get the message that it cannot load the plugin C:\program files\Alwil software\Avast4\ashOutXt.dll
In Outlook, under Options | Advanced Options | Plug-ins, it shows Avast4 active. I can uncheck it, but do not know how to activate the Avast5 plugin for those users.
Uninstall avast from Control Panel (if possible). If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
Run the avast! Uninstall Utility saved on 1. If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after you’ve run it.
Install avast! using the setup saved on 2. Boot.
