I want to take a look at the Data Quality Services feature in the Denali CTP; I happen to have a clean Windows 7 virtual PC image, and have installed the CTP.
Running up the DQS client gave the error:
The SQL Server instance that you are trying to connect to does not include an installation of Data Quality Services. To finalize the installation of Data Quality Services please run the DQS installer script.
For more information please refer to the Data Quality Services installation guide or contact your administrator
So I promptly went to run (as administrator)
C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Binn\DQSInstaller.exe
After a "while" the installer bombs out with:

Reading knowledgebase article 949080 implies that this error may occur is the version of the DLL being registered differs to that in the GAC (strictly, if they have differing MVIDs); but this seems unlikely.
Has anybody been able to successfully install DQS on Denali CTP3, and if so, did you have to do anything "special" to get it to install?
