cannot create a host-only interface in virtualbox 3.1.0

[rosi steiner]

When I will create a host-only interface in the virtualbox-gui the system show the message:

Failed to create the host-only network interface.

I use Win7 X64 german with 4GB RAM. With Virtualbox 3.0.8 and 3.0.12 I can crate a host-only interface.

Do you have a (default) host-only interface created on install?
Could you enable setupapi logging, as mentioned in "Driver Installation Log" section ​here, remove (or backup somewhere) setupapi.log, setupapi.app.log & setupapi.dev.log files and try create the host-only interface.
Once creation is complete (i.e. failed in your case), could you attach the newly-created .log files mentioned above to this report?

Also seeing this on Vista 32bit Host running VBox 3.0.1 r55467. Under File->Preferences->Network clicking 'Add host-only network' results in an error of "Failed to create host-only network interface".

I've tried:

• Removing the existing interface and re-adding it.
  
• Uninstalling and re-installing VirtualBox
  
• Disabling all adaptors before adding host-only interface
  

None of which have made a difference.

System:

• Vista 32bit
  
• 4Gb RAM
  
• Intel Core2 Duo T9600
