No, adding the exclusions will not necessarily ensure that MBAM will update. It has helped some people with this problem, but not everyone. There is another thread on the forums concerning one of the update errors, and in it there are a number of suggestions as to things you can try to solve the problem. I've tried everything in the thread, and still version 1.45 won't update on my computer. I had no problem with version 1.44, so I may go back to it and see if it still updates. If it will no longer update, it looks like I have no other option at this time than uninstall MBAM.
