You can download the installer from the following link: Acrobat Reader and then you can customize the installation path during the setup. Please note the following:
Some components (like shared Adobe services or fonts) may still install to C:\Program Files\Common Files\Adobe.
Updates and patches will continue to apply normally, even if installed on a different drive.
If you're deploying across multiple systems, you can use the Adobe Customization Wizard to preconfigure the install path and other settings.
