I see a trial prompt when I sign in to Acrobat DC on my computer.

When you install and launch Acrobat DC on a Windows computer and sign in, if you see a Try or Buy prompt, do the following:

  1. Exit Acrobat DC, if it is running. 
  2. Download the AcrobatStudentAccess.zip file and extract it on your computer. 
  3. Right-click the included EXE file and choose Run as Administrator. (Click yes or enter your computer password, if prompted) 
  4. Start Acrobat DC. It should now launch without asking you to sign in.
