Neúspěšná aktualizace

Díky za odpověď, ale šlo o to, že pokus o “normální” aktualizaci skončil stejnou hláškou.. Nakonec se to vyřešilo tím, že namísto odistalace Windows jsem použil ten, co je součástí Nortonu. Pak jsem  instaloval výše uvedeným exe (656 mega). Restart počítače a první spuštění Readeru tedy ale trvalo….

​@jizák first of all, you wouldn’t need to uninstall Acrobat for an update. Just let the update do it’s thing and run the update behind the scenes… no, a different can of worms is opened.

You might need to run the Adobe Cleaner Tool, it removes deep registry keys and hidden folders. https://helpx.adobe.com/creative-cloud/apps/troubleshoot/diagnostics-repair-tools/run-creative-cloud-cleaner-tool.html

The file you downloaded is a 2025/2026 version

Try this link to download reader. Delete the one you downloaded, you need a version for your current PC:

https://get.adobe.com/ca/reader/enterprise/

For example, if I am using an old MAC, it’s telling me I need 2022 version

If you have the original email (with direct download link) or registered the 2021 version on Adobe.com, I would download it again the specific .exe or .msp file from 2021, ensure you are running the base installer first, then applying the 2021 update patch.
