driver problem Windows 7 64 bit

I have been using an FPGA board ( http://www.ebay.de/itm/new-fpga-starter-altera-fpga-ep1c3t100-development-learning-board-/121137914993?pt=lh_defaultdomain_77&hash=item1c3461e471 ) for quite some time on my Windows 7 32 bit notebook. Now I want to use my Tower-PC with Windows 7 64 bit.

When I try to use my USBBlaster to configure the board, all leds are turned off while quartus tells me configuration is 100 % successful. When I use my notebook afterwards, leds are working correct so USBBlaster and FPGA board are still working. It must be some driver problem.

I followed this manual ( http://webstaff.itn.liu.se/~qinye/tnge15/manual_install_quartus_usbdriver_windows_7.pdf ) for Windows 64 bit that worked fine on my 32 bit notebook.

Can anybody tell me how to install the USBBlaster driver on Windows 7 64 bit or what else to do ?

It is a Cyclone 1 board so I'm using Quartus 2 9.1.

:confused:

Edit:

I added Pictures for driver path, Installation was successful and driver Details. In driver details you can see that 32 bit and 64 bit dlls seem to have been mixed up. But even when I change it to the right path, my uSBBlaster doesn`t work.
