About 6 months ago I wanted to try Noiseless CK. There was no way to trial it but there was a free download at the bottom of the CK page so I tried it. It opened Luminar and to my surprise no Noiseless CK. I contacted Skylum and they sent me the CK trial. I think because Luminar was a trial I couldn't get it to work so I gave up.
Last week I renewed my interest but on their Noiseless CK page there in no way to buy or try it. I found this during a search.
https://community.skylum.com/hc/en-us/community/posts/360018993091-WHERE-and-HOW-to-purchase-Noiseless-Pro-App-No-link-or-Button- Based on that I decided to try the free Noiseless but it won't open RAW files. When I tried it told me I could purchase CK and I followed that link. Only $17 so I thought I'd try it since they offer it. I think it was $100 six months ago.
It won't let me install the LR plugin even though LR is installed. My guess it does not recognize LR8 even though I have the the latest version of CK. It also does not open Canon 5D4 RAW files properly.
I did read that Skylum thread I posted a link to but I thought I'd follow the path just to see. I did submit a support request to Skylum. Here is the CK page.
