LR Classic not recognizing printer profiles for Red River or Canon papers

Following is a Red River link, it may not be using your specific printer, but that is not so important. What is, and my inquiry, at what point does your failure occur?

So you are stating that when you select to use ICC profiles, you cannot select RedRiver ones?

How about others?

Do you get an error message?

Need a lot more detail. I use Lightroom 8.4.1, a Canon Pixma Pro 100, several different Red River papers and their ICC profiles. I have no problems getting good prints from Lightroom. Is this a problem that just started happening? Is it possible that your print nozzles are clogged? That happened to me a while back. Had to get a new print head.

So it does recognize the profile, you don't like the output? 

You should always test output using good color reference images designed for that task. The color reference images RGB values are such they are set for output and are editing and display agnostic. Test the output this way and examine for the same color issues so we know it's not your image specific issues causing the problems:
