Is Acrobat 7.0 Standard supported on Windows 8.1?

Hi deborahlong,

Here are the system requirements for Acrobat 7: System requirements for Acrobat Professional 7.0, Standard 7.0, 3D and Elements 7.0 (Mac, Windows and Unix for 3D only)

Windows 8.1 is not a supported operating system for Acrobat 7, so you may be able to install/use it, but Adobe Technical Support can't support any issues that may arise from using an unsupported operating system. (For what it's worth, I did find several posts on Microsoft's website from folks who have been able to use Acrobat 7 in Windows 8.1.) But, again, it is not a supported environment.

Best,

Sara
