I'm trying to run the sample Mounter and VDisk project. The driver is installed properly (I do see cbfs4.sys file under Windows/System32/Drivers folder). When I click on "Create Storage", a popup window comes up and asks for the license key. I have the evaluation license key, which I enter. After I click OK, I get the "Incorrect Function" message.

I'm running on Windows 7 Professional 64 bit machine. Using VS 2010.

I did debug the code, and it fails when it calls CreateStorage() method. Error Code is 1. I also checked Event Viewer, and here's what I see in there:
<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
- <System>
  <Provider Name="cbfs4" />
  <EventID Qualifiers="0">1</EventID>
  <TimeCreated SystemTime="2013-01-17T00:50:09.000000000Z" />
  <Security />
- <EventData>

Your help is greatly appreciated.

Please run Mapper sample and see whether it shows version number - this indicates that the driver was installed to the OS properly.

I've run into the same issue with the Mapper and the other demos as well. What was the resolution to this issue? Actually, I found that the error happens when I try to MountMedia after having called CreateStorage. The driver version is
