Am I Installing the Metadata UI Package Correctly?

Question

I downloaded the XMP Metadata UI SDK CC 2014 and per the instructions in the pdf, "To see the results of these definitions in an Adobe application, install the Metadata UI Extension package
in one of the user-specific or general shared resource folders:" I copied (although the instructions say install) these files:
loc folder
schema folder
view folder
manifest.xml
to both of these locations:
WINDOWS: [user]\AppData\Roaming\Adobe\XMP\Metadata Extensions
C:\Program Files (x86)\Common Files\Adobe\XMP\Metadata Extensions
Then launched Photoshop, chose File -> File Info
And I see nothing new in the File Info panel.
What am I missing?
Thanks,

Thanks for the reply Jörg,
I have now place theses files:
loc folder
schema folder
view folder
manifest.xml
in a sub-directory called padam as you mentioned, so the full path is:
WINDOWS: [user]\AppData\Roaming\Adobe\XMP\Metadata Extensions\padam\...
I have not made any changes to the files in the loc, schema, view folders, or to the manifest.xml I downloaded from the Adobe website.
I still see nothing when I bring up the FileInfo panel in Photoshop.
Are there other changes I would need to make in order to see the sample extension show up in Photoshop?
For example, would I need to somehow change the locFilePrefix in the manifest.xml file?
<extension xmlns="http://ns.adobe.com/metadata/extension/1.0/"
   name="com.adobe.sample.extension"
   version="1.0"
   locFilePrefix="sample">
</extension>
Also, in the sampleSchema.xml, would I have to change any of these items in bold:
<xmp_schema prefix='sampleSchema' namespace='http://my.sampleSchema.namespace/' label='Sample Schema for Demonstration' description='This example demonstrates how a new schema can be created'>
<xmp_property name='Boolean' category='external' type='boolean' label="$$$/sampleSchema/Property/BooleanInputLabel=Boolean Field1"  description='$$$/sampleSchema/Property/BooleanInputDescription=Defining Boolean data type'/>
Are there other things I'll have to change in the view folder to get the sample to work?
I guess when I downloaded the SDK and saw "Sample Extension", I was expecting it to work with no interaction on my part just to see the sample. Obviously, I knew I'd have to alter everything to make my own Custom extension.
Thanks for any help you can provide, I really appreciate it!
