adobe acrobat 2020

Hi @jean-claude31846803fxl5 

Sorry to hear about the trouble caused.

If you are still having trouble launching the Acrobat 2020, please try these steps:

1- Restart your computer; sometimes a simple restart is required to run the application correctly.

2- Launch Acrobat, and if it doesn't open, check the Task Manager (Win) or Activity monitor (Mac) to see if it shows in background processes. 

3- If yes, then select all of the Acrobat Processes and End Task or Quit Process 

4- When nothing works, uninstall the application using the cleaner tool:

and download Acrobat 2020 from here: https://helpx.adobe.com/download-install/kb/acrobat-2020-downloads.html 

Thanks,
