Opening PDF files - without signing in

I have recently subscribe to Acrobat Standard nd installed it on my new Desktop PC (Windows 11 home).

Adobe version installed is 24.005.20320,

Everytime I tried to open a PDf file, I get a pop up window to sign in into my account. When I close the pop up window the I am unable to view the PDF file.

Do I I have to sign in into my account before I can open a PDF file to view. If not How do I resiolve this problem.

I have signed into my account and unticked the 'Sync' box underpreferences. I am still having the same problem.

Any help to resolve this problem will be much appreciated

Thank you.
