Server OS not supported?

[REDACTED]

Trying the free AV for Business product.  Installed OK on Win 7 but when we tried to install on a server running Windows Server 2012 R2 it aborted, advising that the product cannot be installed on a server OS. Not sure what is going on?

Hi,

I've not heard of an issue with installing on 2012 R2. Try downloading the full installer package and right click>run as admin. Let us know if you still have issues. Here is a list of compatible Server Os's

Microsoft Windows Server 2003 and 2003 R2 (any edition with latest Service Pack, 32-bit or 64-bit, incl. Small Business Server)
Microsoft Windows Server 2008 and 2008 R2 (any edition with latest Service Pack, 32-bit or 64-bit, incl. Small Business Server, except Server Core)
Microsoft Windows Small Business Server 2011 (any edition with latest Service Pack, x64bit)
Microsoft Windows Server 2012 and Server 2012 R2 (any edition with latest Service Pack, x64bit, incl. Small Business Server/Essentials, except Server Core)
Microsoft SharePoint Server 2003/2007/2010/2013

Thanks!
