Hi Jeff_George,
Thank you for reaching out to Microsoft Community.
Surface Pro X is a Windows 10 ARM based computer. 64-bit applications that have not been ported to ARM64 will not install on the device, some games and CAD software, and some third-party drivers or anti-virus software. New 64-bit apps are coming to ARM 64 all the time. You'll need 64-bit (ARM64) apps, 32-bit (ARM32) apps, or 32-bit (x86) apps. You can usually find 32-bit (x86) versions of apps, but some app developers only offer 64-bit (x64) apps. You may check this page for more details with the Surface Pro X compatibility.
I found here under system requirements that Adobe Acrobat DC comes 32-bit and 64-bit version compatible with Windows 10. I would suggest that you contact also Adobe Support to make sure and to check also if the Adobe Acrobat DC has an ARM based version.
