Decklink SDI doesn't work with win7 ?

Hello,

First I apologize for my English and thank this forum for help.

I have just buy an blackmagic decklink SDI to capture 10 bit 4:2:2 signal coming from my panasonic Ag-f101.

My OS is windows 7, my mother board is an ASUS M4A89GTD PRO/USB3, and i have test to connect the decklink card to both the PCIe 2.0 x4 and x1 port. Firstly i have installed the driver provided in the installation cd, i.e desktop 9_6.4, after reboot the firmware update failed an no capture was possible. Then i have manually installed the last one, 9_6.8, but the message firmware update failed persists, and no signal capture is possible. I have used mediaexpress, adobe premiere but noone detects any input signal comming from my cam. Moreover some options are locked in blackmagic control panel.

I have tested to install it within the same pc but under my linux "ubuntu" boot, and it works perfectly.

My conclusion is there is a probleme with windows 7, someone has any knowledge about this problem, and the way to solve it?

Thanks you very much.
