If you try to install MSTR Intelligence Server onto Windows 8 Preview, the setup will run smoothly with no error, but the service won’t start: the reported error is Failed to start service. Unexpected error occurred. The dependency service or group failed to start
The Intelligence Server depends on several Windows services (more details in technical Note: TN31892); one of which is not present in the Developer Preview of Windows 8.
According to this MSDN article http://msdn.microsoft.com/en-us/library/bb432405(v=vs.85).aspx the Protected Storage service was to be deprecated.
In Vista and Windows 7 is still present but it will apparently removed from Win8.

UPDATE Sept. 21 2011
The solution is to run the Intelligence Server as an application and not as a service in Windows 8. Open a command prompt, go to:
C:Program FilesMicroStrategyIntelligence Server and start it with: MSTRSvr.exe. Now you can use 3 tier connections and web interface. There are some limitation running it as an application, see manuals for details.
