APP -V shortcut issue

Question

Hi,
   Could any one explain me the difference between the below 2 tags.  These 2 tags are taken from the deployment config files
a.      <Extension Category="AppV.Shortcut">
            <Shortcut>
              <File>[{Programs}]\Hyena\Hyena Help (V).lnk</File>
              <Target>[{ProgramFilesX64}]\Hyena\hyena.chm</Target>
              <Icon>[{ProgramFilesX64}]\Hyena\hyena.chm</Icon>
              <Arguments />
              <WorkingDirectory />
              <ShowCommand>1</ShowCommand>
            </Shortcut>
          </Extension>
b     <Application Id="[{ProgramFilesX64}]\Hyena\hyena.chm" Enabled="true">
        <VisualElements>
          <Name>Hyena Help (V)</Name>
          <Icon />
          <Description />
        </VisualElements>
      </Application>
Also could any one explain me what differences I can observe if I change
Hyena Help (V) to Hyena Help in the above 2 tags.

B - In App-V 5, each application has its own Application tag.  This has nothing to do with shortcuts.  You may have multiple shortcuts, or FTAs, etc, registered to an application.
A - This is the shortcut information.  Did you by any chance modify this?  I thought there was an ApplicationId tag in the shortcut block, but maybe if you have only 1 application its assumed or something.  Again, I thought it was always there,
I just checked a few packages and they all have it.
I would not recommend you change the Application ID, unless you have a very good reason to.  It will not affect the appearance of the shortcut to the user.  If you want to change it you can, you just have to make sure every place where the applicationId
is needed you change it to match.   We have changed the ApplicationId, but 99% of the time just edit the shortcut information.
And make sure once you edit the XML, you are importing the new XML into the management console, or using the proper powershell switch!
