>Hi All, I'm just dipping my toes in DirectX waters and have managed to create a Winform that will play audio/video files - BUT !!!! when I try to run the app on a different PC , I receive a pretty useless error message "Error in application" when trying to play a video - digging a bit deeper I find the error is related to not having the DirectX runtime installed , I've tried copying the DirectX dlls to the apps folder but to no avail - any ideas ?


Pete,

I wonder whether just copying the dlls is sufficient

I think the DirectX runtime has to be installed (properly) on that pc http://www.microsoft.com/downloads/details.aspx?FamilyID=2da43d38-db71-4c1b-bc6a-9b6652cd92a3&DisplayLang=en
Maybe you can get away with registering some dlls - but I do not know which

I'd try the installation
