Error 18 When Publishing Online in Adobe InDesign 21.3

Hi, I’m now having the issue of being unable to uninstall CC because I can’t seem to uninstall Camera Raw, even though I’ve followed what seem to be the right steps to do so. Anyone able to help on this front? Thanks

Start with the obvious (you may have already done this, but it fixes a lot of cases):

• Sign out of Adobe Creative Cloud (desktop app)
• Sign out via Creative Cloud on the web
• In Adobe InDesign go to Help → Sign Out

Reboot, then sign back in everywhere

If that doesn’t resolve Error 18, it’s usually a caching/auth issue rather than connectivity. Next steps:

Quit all Adobe apps

• Clear the Creative Cloud cache (delete the OOBE folder):
• Mac: ~/Library/Application Support/Adobe/OOBE
• Windows: C:\Users\[username]\AppData\Local\Adobe\OOBE

Relaunch Creative Cloud and sign in again

If it’s still failing:

• Try publishing from a different network (rules out firewall/proxy issues)
• Disable VPN if you’re using one
• Check system date/time is set automatically (Adobe auth can fail if it’s off)
• As a last step, reinstall the Creative Cloud desktop app

Error 18 is almost always authentication getting stuck somewhere, not your document or internet connection.

Very last resort
