Hi Antonio,
which version and sp of BPC have you installed? From your answer I suppose bpc 10 and sp > 6, isn't
it? Which sp for epm add-in?
In the note of 5 december 2013 1823786 - Does SAP BPC support Windows 8 and Office 2013? it's written that BPC 10 will support windows 8, now 8 is supported but I think that for 8.1 it's too early, I didn't find notes about it.
I would ask directly to SAP to know if supported and if so why the matrix isn't updated.
Regards
Roberto
