@paavo_5282 wowza, your installation is definitely corrupted! You tried to uninstall, but it is giving you mondo issues? Use the Adobe Cleaner from Adobe's website to 'purge' dead small files. https://helpx.adobe.com/ca/creative-cloud/apps/troubleshoot/diagnostics-repair-tools/run-creative-cloud-cleaner-tool.html this tool will fix common issues, such as removing outdated Adobe software, cleaning corrupt files, and repairing host files for Adobe server connectivity. Just quit from Adobe Acrobat both from online and Creative Cloud Desktop app. Run the Cleaner tool, follow the instructions on the screen. For good measure, I would also remove the adobe preferences in your computer (if you are on a PC, may nay need to turn on show hidden files?!) And remove those Adob Acrobat preferences from your computer. Restart your computer so that it can create new preferences, and log back into Creative Cloud Desktop app. and download a brand new and fresh Acrobat (don't use the previous one, that might be corrupted!) and install th correct Windows 11 64 bit for your computer.
