Extension Manager CC does not know that Photoshop CC 2015 is installed

Hi everyone,

I am trying to learn how to make extensions for Photoshop CC 2015 with Adobe Extension Builder 3

I have edited the manifest like:

<HostList>

            <Host Name="PHSP" Version="[15.0,15.9]" />

            <Host Name="PHXS" Version="[15.0,15.9]" />

        </HostList>

Since Photoshop does not load the files generated by Eclipse or Bracket, I generated an XMP file.

Well now the Extension Manager gives thee following error:

This extension can not be installed, it requires Photoshop version in range of inclusively between 15.0 and 15.9

How come????????????????????????????????????????????????????????????????????????

Everything is up to date since "IT IS THE CLOUD"
