Adobe's Creative Cloud or CC can provide you with a few different versions of Lightroom depending on when you signed up/installed. This can cause a bit of confusion when filling out the order forms: Input/Output File types.
The most recent desktop version of Lightroom is Lightroom Classic CC (7.0).
If you are unsure go into your Creative Cloud apps location and see if the 'Update' button appears. If so go ahead and update. This will then provide you with the latest LR version (Classic/7.0 release). Please note there is also a cloud based version of Lightroom called: Lightroom CC. Contact Adobe directly if unsure of which version you are running.
If you are running an older version of Lightroom this might be LR4, LR5, or LR6 (Adobe Lightroom CC). Check the version by opening Lightroom click on Help > System Info
****Please note we no longer accept LR4 version.
