Thank you for the reply and the information which is most helpful and kind of you. I have installed 11.3 by following the link to the correct download page as shown in your reply. However, and there always seems to be one of those. I installed Reality 4 for Poser in the old version, and now find its no longer showing in 11.3. I had to use the Snarlygribbly fix to install Reality and I followed the install path and find everything is intact, so what's happening there...Again thanks in advance for any info
