I bought the downloadable version of LR5 last November. When I download it now onto my new computer the serial number is not accepted. I've tried contacting Adobe but they direct me to a webpage that is also no helpful. Any ideas?
This is usually due to downloading the CC version in error (common presumably as it's harder to find the standalone one).
Uninstall the version you have and go here for the standalone one:
For Mac:Adobe - Lightroom : For Macintosh : Adobe Photoshop Lightroom 5.6
For Windows: Adobe - Lightroom : For Windows : Adobe Photoshop Lightroom 5.6
If this is not the case then we'll need more details.....
