You'll find this file (and other required files) in the SAS Integration Technologies client folder. On my machine these are in:
C:\Program Files\SASHome\Integration Technologies
OR
C:\Program Files\SASHome\x86\Integration Technologies
depending on whether you're using 64-bit or 32-bit PowerShell. You should add this to your system search PATH environment variable.
