Thanks for the assist all, running the DX set-up in the steamapps-common folder works perfectly. Thanks again

ARMA 2 sound does not work on windows Vista 64 at all, I understand this issue has been discussed already, although there is still a very serious issue. To fix the sound problem, the 'March' http://www.microsoft.com/downloads/details.aspx?FamilyID=0CF368E5-5CE1-4032-A207-C693D210F616&displaylang=en version of DX10 needed to be downloaded, unfortunatly, i went straight to microsoft and downloaded the latest version, 'June' http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=822640ab-0983-4c41-9c70-632f6f42c557 which does not work for some reason. Unfortunately also, there is absolutely no way to backtrack through versions of Direct X. This is a very serious issue as this game cannot be played without sound and it is irritating to be penalised for downloading the latest version of DX10 instead of a specific version. This is a problem which will be a encountered by many users and is one that needs to be addressed immediately. EDIT - Problem sorted. If using with steam then go to steam apps> common> ARMA 2 demo> DirectX and run the Direct X setup there for the correct version of DX

Agreed, later versions of DX cannot be installed over the top, it doesn't allow this as it simply detects that a newer version is installed and takes 'no further action'.
