The Toolkit should work fine in the 32 bit (aka SysWow64) PowerShell runtime. I suspect that your toolkit may not be installed correctly, in particular make sure that the module files aren't blocked. See this post for more info: https://communities.netapp.com/message/74639#74639
You probably want to unblock the zip file before extracting the contents to the 32bit module dir: C:\Windows\SysWOW64\WindowsPowerShell\v1.0\Modules
Note that recent versions of the installer script (Install.ps1, available in the download section) should do the unblocking step automatically.
Edit: Also, please double check your execution policy in 32bit powershell with Get-ExecutionPolicy.
