Acrobat Pro 2020 crashes every time I open it

[donJulio]

I just installed Acrobat Pro 2020, upgrading from Acrobat Standard XI. Every single time I try to open the software it crashes. Whether I try to open the software by itself, or am double-clicking a PDF file in Windows Explorer, either way it crashes in one second. I don't even have time to go into preferences to try and change any settings. What can I do so this software works as it should?

Hopefully, you uninstalled Acrobat Standard 11 first. If you haven't, uninstall both Acrobat Standard 11 and Acrobat Pro 2020. Reboot and then re-install Acrobat Pro 2020. Contrary to what some may think, you really cannot have parallel installations of either two versions of Acrobat or Acrobat and Reader.

Let us know if that helps.
