Ive noticed posts about this problem in the forums but never seen a solution to it?
Im running windows 7 x64 with 32-bit Office 2010.
When re-installing NIS 2012 19.8.0.1 all works fine until I run LiveUpdate.
Once LiveUpdate downloads and install the 142 Mb update to get it to 19.9.1.14 its back to slow loading of Outlook where it freezes for 20 seconds at the splash screen (while loading the Anti-Spam plugin). Unchecking this in Outlook and it loads properly fast again but would be nice to have the Anti-Spam option working again. Computer is fitted with SSD and usally load Outlook in a couple of seconds.
