I suggest to download and install the latest LR5 (5.7.1) directly from here: Download Photoshop Lightroom
There's no need to install 5.0 from CD first.
Post back if you still encounter issues with this version.
Thanks. Ill give it a go and let you know..
Worked a treat. Thanks very much.
I got the same error and have downloaded it from that link (as per costumer support) BUT i still get the SAME error!
Customer support that L5 is not supported anymore and it has to be through this forum but no one's been able to give me an answer
I bought a new MACBOOK Pro 2017 and tried to install my L5 through my product installer. Please advise.
Same happened to me. It won't launch after installation, and was told by inept and stupid people in India that they no longer support lightroom 5. Therefore, you've just gifted us $100. Oh by the way, can I interest you in a overpriced subscription service where we have a constant revenue stream. We aren't interested in you, just making money off of you.
This is some seriously bad customer service by adobe. I will no longer support adobe, and will spread the word. Nobody should support this kind of horrible service. It would be easy to find a work around, but the incompetent tech support half way across the world sends me to this page. They know exactly how to fix the problem. they choose not to.
I've encountered some websites that alter installation certificates on the Mac OS, but none really tell you much. Anybody have any ideas?
Did you notice that this is an old and answered thread ... please open a new thread with more details regarding the issue like exact OS version, exact Version you are trying to install and 'word-by-word' error messages.
