check processor architecture and proceed with if statement - powershell

Question

i know that here are a lot of examples how to get the processor architecture.
this should get the type with true or false checking on x64
my question is: how do i get this output into a if statement?
example: if it is an 64bit processor THEN perform a few steps and if it is 32bit then perform other steps. how can i go on further?
i tried a few versions of code but also got true or false back which is ok but how to go on further?
can you help me out guys?
thanks

Answer 1

thank you all.
i solved it by using the following:
$os_type = (Get-WmiObject -Class Win32_ComputerSystem).SystemType -match ‘(x64)’
if ($os_type -eq "True") {
Write-Host "i am an 64bit OS"
write-host $os_type }
else {
$os_type = (Get-WmiObject -Class Win32_ComputerSystem).SystemType -match ‘(x86)’
if ($os_type -eq "True") {
Write-Host "i am a 32 Bit OS" }

Answer 2

[System.Environment]::Is64BitProcess returns true or false, so it's a very simple if statement.
if ([System.Environment]::Is64BitProcess) {
# Do 64-bit stuff
} else {
#Do 32-bit stuff
}
You didn't specify which of the "lot of examples" you're using, so I showed the method I use.

Answer 3

Could also use the environment variables.
$Is64bitProcess = $env:PROCESSOR_ARCHITECTURE -eq 'AMD64'
$Is64bitOs = $Is64bit = $env:PROCESSOR_ARCHITEW6432 -eq 'AMD64'

Answer 4

thanks for your input!
i tried for example this:
Thank you for your answer! i tried for example the following:
echo "check if 32 or 64bit OS"
$var = (Get-WmiObject -Class Win32_ComputerSystem).SystemType -match ‘(x64)’
if ($var = "True") {echo "i am an 64bit OS"
#setting the current directory as the directory the script is in
$sourcenssm= Split-Path -Parent $MyInvocation.MyCommand.Definition
#setting the targetdirectory for nssm
$targetnssm="C:\Users\cp\Desktop\nssm.exe"
#setting the current directory as the directory the script is in
$sourcewts= Split-Path -Parent $MyInvocation.MyCommand.Definition
#setting the targetdirectory for wtswatchdog
$targetwts="C:\Windows\wtswatchdog.exe"
#copying nssm to target - WORKING
if (-not(Test-path $targetnssm)) {Copy-item -Path $sourcenssm\nssm.exe -Destination $targetnssm}
#copying wtswatchdog to target - CHECK!
if (-not(Test-path $targetwts)) {Copy-item -Path $sourcewts\wtswatchdog.exe -Destination $targetwts}
}
but it gives me everytime 64 bit as an output also if i am checking
echo "check if 32 or 64bit OS"
$var = (Get-WmiObject -Class Win32_ComputerSystem).SystemType -match ‘(x86)’
if ($var = "True") {echo "i am an 64bit OS"}
then it is also going to the echo-part.

Alroc's answer works for powershell 3.0 or above i believe. In case there is an issue with that another approach would be this:
$architecture = (Get-WmiObject win32_processor | Where-Object{$_.deviceID -eq "CPU0"}).AddressWidth
If ($architecture -eq 64) {
# Do 64-bit stuff
} else {
#Do 32-bit stuff
}
