Lightroom 6 dows not recognise Canon 5d Mark IV raw files

Question

Hello,I have the last iteration of the "perpetual license" Lightroom 6 with Camera Raw 9.When trying to import files by Canon 5D Mark IV the preview thumbnails appear grey with a message "Preview unavailable for this file" (screenshot).The files are the regular type, not dual-pixel and are in both sRGB and Adobe RGB colour spaces. My PC runs on Windows 10. I am aware that this issue has been around since around 2017 at least but I could not find a working solution so please help with advice. Thanks. Simeon

This time it worked from your link - thanks a lot for helping. Mut be I had an older installer.

This seems not from the links that @Per Berntsen and I posted. In the posted links are installation files for the latest version of the perpetual Lightroom 6 version (6.14).

I don't know which link you've used, you installed a subscription based version, as @Rob_Cullen wrote.

Do you ask for an upgrading your catalog file after you start Lightroom?

The only way to fix it is a complete clean reinstallation of Lightroom 6. But beaware and deactivate your recent installation. Lightroom (Legacy v6.14) does not work if you have the Creative Cloud Desktop App installed. The desktop App converts Lr6 to Lr CC1025 which requires a paid subscription.

I can only suggest the following clena reinstallation without the CC client

Backup all personal data, like templates, presets, catalog(s) etc.
Uninstall everything cc including preferences, https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html
Then uninstall the cc desktop app, https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html
Clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html
Restart your computer (don't skip this)
**DO NOT Reinstall the cc desktop app,
Install Lr v 6.14 using the 'Offline' method suggested by @kglad @ LIGHTROOM 6 -OFFLINE ACTIVATION

This is now the only way known to install, activate and use Lr6.14

Check in your Adobe account if you have a subscription; login with your Adobe ID. If there's a subscription listed you must cancel it. Please take a look here:
