Run the installer that you downloaded from your VSCO account and select or un-check the camera support you'd like installed (you can always update what you want installed or removed in the future). We suggest choosing the Standard option as those presets will be used for any cameras that do not have custom camera profile support as well as color grading video. To optimize performance, only choose the components you need.
Next, you'll be prompted to enter your license key. Lastly, restart Lightroom or photoshop after running the installer.
We have made a video that walks you through the Adobe Lightroom CC, 6, 5, & 4 install, to watch it click here.
If you have any issues with your License key check out this support article and if you have any issues finding them once they are installed try this article.
