CASK is starting to move to the front burner with the birth of http://www.amarillo.us.com/; in the new year Global Webnet, LLC will be looking to provide the Amarillo Business Community with a higher visibility in the Internet Community.   Mainly because of the last 4 bookings my wife received (she is a professional Videographer/Photographer) they all said they found her on the Intefrnet.  

My attempts to create a new release for CASK were greeted with the error "The installer was interrupted..." as shown in Figure B.

Figure A.

My first reaction/assumption was it was because of my new Vista Ultimate x64 development environment so I set the TargetPlatform to x64 (see above) with no luck - I was still getting the following error:

Figure B.

Googling this error resulted in a lot of different applications having the same problem with users asking the same question; this was turning into quite the adventure....

With no solutions being offered for my early Googling efforts I was very happy to see the following solution - unfortunately when I attempted the aspnet_regiis -i command I was greeted with a response that said IIS was not installed - as you can see it is installed and works....

Figure C. 

The only thing I could think of was perhaps it had to do with IIS Compatibility mode - so I went into Control Panel, Program and Features and added IIS 6.0 Management Compatibility.

Figure D. 

Unfortunately, this did not make aspnet_regiis any happier - it still reported that IIS was not installed.   I suspect this has something to do with this .NET 2.0.50727 command no longer being valid with IIS 7, .NET 3.5 w/SP1.

HOWEVER!!!!  My Web installation problem went away!   I am now able to install my new CASK installation application without issue :)

My assumption would have to be that IIS 6.0 Compatibility Manager is required for Vista Ultimate x64, .NET 3.5 w/SP1 Web Installations.   Whether this is the case for your issue???  We can only hope.
