Adobe acrobat for some reasen removed itslef from my computer after running an update. when i try to download it from the website it displays an error message

Adobe Acrobat reader has removed itself from my computer. When trying to download it again from the website an error message appears saying 'Newer Version already installed'.
I have searched the programs list on my computer and Adobe in any form does not appear.
How can i install this program again?

A response ASAP would be appreciated. As a university student I rely on this program to access a lot of my materials.
