Why Acrobat 2017 is not supported on Windows 8.1?

Hi Bernd,

Thanks for your quick response!

I am afraid that I am not able to agree with your comment "Windows 8.1 is Windows 8". Because in the system Requirement doc for Adobe Acrobat 2015, Windows 8 and Windows 8.1 are mentioned as two different OSes:

Windows

• 1.5GHz or faster processor
• Microsoft Windows Server 2008 R2 (64 bit), 2012 (64 bit), or 2012 R2 (64 bit); Windows 7 (32 bit and 64 bit), Windows 8, 8.1 (32 bit and 64 bit), or Windows 10 (32 bit and 64 bit)
• 1GB of RAM
• 4.5GB of available hard-disk space
• 1024x768 screen resolution
• Internet Explorer 8, 9, 10 or 11; Firefox (ESR)
• Video hardware acceleration (optional)

From the same URL, if "system requirements for Adobe Acrobat Pro 2017, Acrobat Standard 2017" is selected, the statement is different:

Windows

• 1.5GHz or faster processor
• Windows Server 2008 R2 (64 bit), 2012 (64 bit), 2012 R2 (64 bit), or 2016 (64 bit); Windows 7 (32 bit and 64 bit); Windows 8 (32 bit and 64 bit); or Windows 10 (32 and 64 bit)
• 1GB of RAM
• 2.5GB of available hard-disk space
• 1024x768 screen resolution
• DVD-ROM drive required (if installing from disc)
• Microsoft Internet Explorer 8, 9, 10 (Windows 8 minimum), or 11; Firefox (ESR)
• Video hardware acceleration (optional)
• This software will not operate without activation. Internet connection and registration are required for software activation, validation of subscriptions, and access to online services.*  Phone activation is not available.

It is a bit odd since Windows 8 has reached its end of life a couple of years back. That's why I want to clarify this.

Thanks!
