PashaF Apr 21, 2011 at 7:10 PM I have downloaded the latest release 0.3.1.1 installer and, unfortunately, was not able to complete the installation (log file below). I also attempted to manually install and register the module; however, it failed as well.  I copied the module files into the required directory and then ran 'import-module powerSSAS' command.  No errors were yielded.  However, the command 'Get-ASConnection localhost' failed with the following error: ```Get-ASConnection : The SelectCommand property has not been initialized before calling 'Fill'. At line:1 char:17 + Get-ASConnection <<<< localhost + CategoryInfo : NotSpecified: (:) [Get-ASConnection], InvalidOperationException + FullyQualifiedErrorId : System.InvalidOperationException,Gosbell.PowerSSAS.Cmdlets.CmdletGetASConnection ``` `Log file:` ```Running a transacted installation.

Can you test if the get-ASServer works for you? I'm not sure why the installer is throwing an error, but we should be able to get the module install working.
