LR 5 disc upgrade problem
I have LR4 on my IMac and purchased LR5 upgrade disc but the computer won't read the disc. Disc is okay as I have uprageded successfully on Macbook pro. I did have LR5b on Imac but have dumped this programme to trash thinking that there may be a conflict.
Don't know what to do next, any advice ?
Why are simple things difficult?
