Upgrad to X2, No folder netfx_extended_X86

[NormanDerrick]

Hi,
I just installed the upgrade to IA X2 and when I try to build by previously existing project an error is raised as follows:
No files matching wildcard pattern
C:\PROGRA~2\INSTALL~3\runtimes\netfx_extended_x86\*.*

My prior install (IA 18) included two folders under .\runtimes as
.\netfx_extended_x86
.\netfx_extended_x64

After upgrading to X2, the only similarly named folder under .runtimes is
.\netfx_extended

When I ran the install I selected all features. Is there another step that I need to run to have the separate folders for _x86 and _x64 created? In case there is some effect based on the O/S, I am using Windows 8.1

Thanks
Norm Derrick

Never mind.
I created a new test project and found that the default reference is no longer qualified by the CPU architecture.

Thanks,
Norm
