directx 9.0

[Andrew]

I have just downloaded directx 9.0 from microsoft and I
received 2 error messages which stated dpnet.dll and
dpnhpast.dll are not valid window images, pretty amazing
considering I have windows XP and I downloaded this stuff
from windows, talk about doctor heal thyself.
Anyway can anybody suggest anything?

Are you running at least SP1 for Windows XP, Andrew, and do you have
Cryptographic Services enabled in Control Panel/Administrative
Tools/Services? Have you done any "tweaks" by disabling services?

 

[Andrew]

Thanks for the reply
I've just checked the Cryptographic services and it is
enabled. I am not aware that I have done any 'tweaks' and
I get regular automatic updates from windows for my
windows home edition which have SP2 in brackets, so I
presume I have at least SP1
