Ive had Creative Cloud for ages and done all the updates but am still on Lightroom 5 and havent got the dehaze tool. Why? And how to I fix it?
You need to login to the Creative Desktop app using your Adobe Id & password on your machine and install Lightroom CC 2015 to get the Dehaze Slider.
Lightroom CC 2015 is the upgraded version which came out after Lightroom 5, so it will install individually on your machine.
You can refer the download link for the Creative Cloud desktop app, if in case its not installed on your machine. : Download Adobe Creative Cloud apps | Free Adobe Creative Cloud trial
Lightroom CC 2015 requires a 64-bit operating system. If you are using a 32 bit operating system then Lightroom 5.7.1 is the most recent version that you can install. If you have a 64-bit operating system then you need to do an update because Lightroom 5 has been completely replaced by CC 2015.
