I have spent the last couple hours trying every single fix available online from all forums and websites writing on the topic. I cannot get this to work for the life of me, and need this fixed as soon as possible to run Lightroom for some work stuff.
Have already tried re-downloading the installer multiple times and re-installing each time
Tried downloading 5.3 and same outcome
Tried copying preference files and registration files from a different user account that I created (yes it ran fine on that account but I cannot have it there, I need it running on my main user account)
Any help you can offer would be much appreciated; as I said I have spent hours online already reading articles and trying everything.
Running on brand new 27" iMac with OSX 10.9.3
Thank you!
