Hello,
this looks like the issue with registration of the SDK libraries. Typically this might happen when you install th Orion SDK under non-administrative account.
To register the SWIS PowerShell snapin on 32-bit Windows computers:
Run the following command, all on one line. C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\InstallUtil.exe 'C:\Program Files\SolarWinds\Orion SDK\SWQL Studio\SwisPowerShell.dll'
To register the SWIS PowerShell snapin on 64-bit Windows computers:
Run the following command, all on one line. C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\InstallUtil.exe 'C:\Program Files\SolarWinds\Orion SDK\SWQL Studio\SwisPowerShell.dll'
I hope this will help.
