6.3 just about/ 6.4 conmputer says no! - Please help

[Moose]

Really keen to play this mod but after an install of both 6.3 and 6.4 I get this message:

'Kindgoms.exe - entry point not found' it then goes on to explain: 'the procedure entry point Direct3Dcreate9Ex could not be located in the dynamic link library C:\\windows\system32\nvspcap.dll'

I'm using windows 8.1 and have a non-steam version of Kindgoms patched to most recent. I can get 6.3 to load and display eventually (after repeatedly cancelling the pop-up message) but 6.4 loads with no screen display (I can hear the music in the background).

Any advice really welcome

thanks

Moose,

Install mod outside of Program Files, report back

Thanks mate although I already copied the entire Medieval folder to C:Games and then installed SS there, so this approach has been tried outside of Program files.
