Powershell x86 query not working

Is the Connect-Swis portion working correctly (generating your $Swis variable)?  If that part fails, it might be that the PowerShell x86 doesn't recognize the SwisPowerShell module.  More recent versions of the shell will automatically import modules as needed, but I think that was a Windows PowerShell 5.1 and later thing.

Can you share your error messages and the output of $PSVersionTable while in the x86 shell?

There's two boolean static methods in the Environment you can inspect and compare, one looks at the PowerShell process, one looks at the underlying upsers OS.

if ([Environment]::Is64BitProcess -ne [Environment]::Is64BitOperatingSystem)
{
"PowerShell process does not match the OS"
}
