I apologise if this question has already been answered, but when I try to install 8.5 I get the following errors:-MSI errors 1603 and 1708
Installation error RC=851
The install fails. If I try to remove my existing version of Notes (8.01) using the MS software removal tool I get “this upgrade option is not supported”
So being caught between a rock and a hard place, how do I get 8.5 to install?
