# Often, a 32-bit binary needs to call a 64bit binary or registry hive.
# Place the following code at the very top of a powershell script to determine if powershell.exe is being invoked as a 32bit process, redirect it to use 64bit, then continue executing whatever follows.

# Relaunch in x64 powershell if not already
