When I was using Windows 7 x64 operating system, I could successfully install and use RightsManagement ES2 Extension for Microsoft Office( Of course, with some bugs which I have mentioned before).
Now, I upgrade to Windows 8 x64, I find that I cannot install it.
When do you plan to support Windows 8 and Office 2013?
Please refer to the documentation
● Microsoft Windows® Vista or Windows 7 (32-bit and 64-bit)
● Microsoft Windows XP (32-bit)
● Microsoft Office 2003, 2007, or 2010 (32-bit)
Adobe is in the planning stages for the next release of the plugins, a timeline has not yet been set
