I am upgrading from Elements 11 to Lr6. When I try to upgrade the catalogue to Lightroom I get an error message "Lr encountered problems when trying to update the PE catalogue and cannot complete the operation" How do I resolve this issue so that I can use Lr?
I am not an expert in this area. It might be helpful to first upgrade your Element 11 catalogue to the latest Element version (v13? via trial download, backup first). Then try to update to Lr from the upgraded Element 13 catalogue.
