help using the azure gateway for the new azure analysis services?

hi all,

i'm trying to use the new prevew azure analysis services (to have a non-VM way of putting my tabular model into the cloud), and it directs me to install/config the azure on-premise gateway:

https://azure.microsoft.com/en-us/documentation/articles/analysis-services-gateway/

i receive the following error from the install program:

System.ComponentModel.Win32Exception (0x80004005): Application not found
at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startInfo)
at System.Diagnostics.Process.Start()
at System.Diagnostics.Process.Start(ProcessStartInfo startInfo)
at Microsoft.DataProxy.EgwInstallBA.ViewModelBase.<get_HyperlinkCommand>b__8(Object param)
at Microsoft.DataProxy.EgwInstallBA.RelayCommand.<>c__DisplayClass6.<Execute>b__4()

anybody have any idea what gives?

thanks for any suggestions,
