Have an iMac 27" Running OS 10.12.3 3.2 Ghz Intel Core i5 24Gb memory
Subscribed to CC with Photoshop and Lightroom several days ago. Recently advised of update to LR so tried to do that. Told that couldn't be done as running two copies of Lightroom!!! Tried to delete the supposed second copy using instructions on support several times to no avail. Deleted LR and then tried to download again. Told couldn't do update which I wasn't after and the message was Error 29 download error. I have no idea what to do next so can anybody help
Many thanks for this as it solved the problem. I am still a little confused as I had gone through the route you gave me before. However the only difference is that before trying your suggestion I had logged out and closed down my computer overnight. Anyway never mind it's all solved and I can start getting to grips with Lightroom.
