Detecting if PowerShell was opened as 32bit process

Dylan November 12, 2015

I’ve started to automate a ton of things in our environment using PowerCLI (VMware). Unfortunately some of the cmdlets require a 32bit powershell, in order to protect vCenter from bugs via running the script as a 64 bit process I have had to implement a way to make sure it was run as 32bit. Im sure this can be handled a few different ways but this is working great so far.

$is32bitcheck = ([Environment]::Is64BitProcess)

if ($is32bitcheck -eq $true) {
    Write-Host "PowerShell was not opened as 32bit process, please open as 32bit process!" -ForegroundColor red -backgroundcolor black
    Write-Host "Press any key to continue ..."
    $x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
    Exit
}

$is32bitcheck = ([Environment]::Is64BitProcess)

if ($is32bitcheck -eq $true) {

Write-Host "PowerShell was not opened as 32bit process, please open as 32bit process!" -ForegroundColor red -backgroundcolor black

Write-Host "Press any key to continue ..."

$x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")

Exit

}
