I cannot install lightroom 5 until the upgrades from 4 are on the pc,
You don't need to have Lightroom 3 and 4 installed on your computer to install Lightroom 5. Just install Lightroom 5 and input your serial number for 3 in the previous version box and your serial number for 5 in the upgrade box.
Thank you, I took the plunge and bought Adobe CC, couldnt afford anymore downtime on editing, seems to be working so far! Much appreciated for the reply though!
Oh the other reason that I always install prev version of lightroom is that the slideshow export on 5.4 seemed to jitter a little with the music which doesnt happen with 4.4. I hope its been sorted out with 5.5, otherwise I will have to try somehow to get 4.4 back on...
