Is using [intptr]::Size to check 32bits vs 64bits relevant?

In a deployment Powershell script, made by an editor, it use the following lines to determine if the server is 32 bits or 64 bits and download the appropriate package.

if ( [intptr]::Size -eq 8 ) { 
   $sourceUrl=-join($baseurl, "software/agent/Windows/x86_64/") }
else {
   $sourceUrl=-join($baseurl, "software/agent/Windows/i386/") }

I have found one example of [intptr]::Size returning value 4 and the system is 64 bits on a Windows 2008 R2 server.

So should I consider the above method not right ? And which alternative can I use ?

Solution 1:

if ([Environment]::Is64BitOperatingSystem) { 
  $sourceUrl=-join($baseurl, "software/agent/Windows/x86_64/")  
}
else {
  $sourceUrl=-join($baseurl, "software/agent/Windows/i386/")  
}
