Why is the 'demo' adaptor missing from the list of InstalledAdaptors in Image Acquistion Toolbox 3.0 (R2007b)?

In Image Acquistion Toolbox 2.1 (R2007a), there is a 'demo' adaptor listed as InstalledAdaptors

imaqhwinfo

ans = 

      InstalledAdaptors: {'coreco'  'dcam'  'demo'  'winvideo'}

          MATLABVersion: '7.4 (R2007a)'

            ToolboxName: 'Image Acquisition Toolbox'

         ToolboxVersion: '2.1 (R2007a)'

This is not the case in MATLAB R2007b.

imaqhwinfo

ans = 

      InstalledAdaptors: {'coreco'  'dcam'  'winvideo'}

          MATLABVersion: '7.5 (R2007b)'

            ToolboxName: 'Image Acquisition Toolbox'

         ToolboxVersion: '3.0 (R2007b)'

This bug has been fixed in Release 2007a (R2007a). For previous product releases, read below for any possible workarounds:

The ''demo' adaptor is not registered by default anymore. It is possible to use it however using the following commands:

imaqregister([matlabroot '\toolbox\imaq\imaqadaptors\kit\demo\mwdemoimaq.dll']);

imaqreset

imaqhwinfo

ans = 

      InstalledAdaptors: {'coreco'  'dcam'  'mwdemoimaq'  'winvideo'}

          MATLABVersion: '7.5 (R2007b)'

            ToolboxName: 'Image Acquisition Toolbox'

         ToolboxVersion: '3.0 (R2007b)'

The adaptor should work as before, but with a different name (mwdemoimaq).
