It seems like everyone is having the same problems....
we should not be having this problem.. to install updates that do not work....
Add me to the list of problem update installations..
Following this posts advise... I selected "Control Panel", "Add/Remove Programs", LogBook Pro". This brought up the LogBookPro installation screen which gave me an option to "remove components" "reinstall" or "totally remove"...
The "reinstall" option seems to have repaired what was wrong, without having to do a complete "remove, download and install" routine.
