Tools - Wrong Install Path for Windows Architecture

Objective:
Install XenTools for a fresh Windows 2008 R2 (64-bit) Guest OS using local Administrator account

Expected Outcome:
XenTools installer defaults the install path to C:\Program Files\Citrix\XenTools\ (based on the OS' architecture and to follow the Guest VM's filesystem layout)

Actual Outcome:
Default path is shown as C:\Program Files (x86)\Citrix\XenTools\

Reason for Filing:

• During Creedence Alpha/Beta, this path was detected for Windows 2K8, 2K3, as well as 2012 at some point
• Due to the nature of Tools' rolling upgrade/installer, I never alter the default install path during an initial setup of tools

Additional Information:
From the environment, the architecture is visible in Visual Studio referencing $(PROCESSOR_ARCHITECTURE) – much like 'set' from the command line to get:

PROCESSOR_ARCHITECTURE=AMD64
PROCESSOR_IDENTIFIER=Intel64 Family 6 Model 26 Stepping 5, GenuineIntel
PROCESSOR_LEVEL=6

Did anything change in the install logic to detect the Guest VM architecture and default install path?

Thanks!!
