Today I fixed a glitch in OSR’s ddkbuild.cmd which would cause WDF builds to fail. Grab your fresh copy at the DDKWizard website or OSR. The version should be 7.0beta4a. If it is not, check back later since OSR should upload it soon.
And don’t hesitate to contact me about the .cmd version. It was feedback of a user that revealed this problem!
