I tried to run SIOCTL sample built as 32 bit debug on windows 8 x64 build 9200 system. It fails to load sample driver with error 1275 (ERROR_DRIVER_BLOCKED, This driver has been blocked from loading). Have just downloaded WDK sample and run with VS 2012.
What I did wrong and what are possible workarounds?
System boot have debug and testsigning set, selfsigned cert is in trusted root store. Debug cable was not connected.
