LUT Pack installed and not found

Hello,
I've downloaded a Retro-LUT Pack from Adobe and installed it correctly. Now i cant find the .cube-files in any directory to use them. I have searched the whole computer without a trace. I paid for it, so I want to find and use it! I used the recommended Anastasiy’s Extension Manager for installing. It was shown as "installed" in the Creative Cloud Desktop Manager. Can anybody give advice where to find the data? The "Where to find it" site that should solve my problem was very disappointing and unhelpful.
