I have a Zynq ZC706 board and I'm having this exact issue. The digilent drivers don't install correctly. I've tried several methods including running the wrapper.bat file and using wdreg directly. The problem seems to be with the windrvr6 driver file. If I try to install the latest adept, I get an 80030000 error. Using wdreg I get access is denied errors copying the inf file. But I'm running from an administrator cmd prompt.
C:\Windows\inf>f:wdreg -compat -inf f:windrvr6.inf install
WDREG utility v10.21. Build Aug 31 2010 14:21:54
