<p>You might run into a problem when trying to Add administrative templates in GPO on Windows Server 2012 R2.</p>
<p>After you have downloaded the administrative templates from Microsoft website and tried to add a new template using Add/Remove Templates in GPO you have probably run into a problem.</p>
<p><a href="https://www.wincert.net/wp-content/uploads/2018/05/admin-templates.png"><img class="alignnone wp-image-2599 size-full" title="administrative templates" src="https://www.wincert.net/wp-content/uploads/2018/05/admin-templates.png" alt="administrative templates" width="448" height="282" /></a></p>
<p>When browsing the folder with administrative templates you can&#8217;t select any template that can be added to the policy.</p>
<p>In order to solve this you have to do the following:</p>
<p>Copy the ADMX files to:<br />
<strong>C:\Windows\PolicyDefinitions</strong><br />
or if you&#8217;re using a Central Store the location should be:<br />
<strong>\\%yourdomain.local%\SYSVOL\%yourdomain.local%\Policies\PolicyDefinitions</strong></p>
<p>Now, copy the language files from <strong>en-US</strong> or other folders, depends on the language you are using to:</p>
<p><strong>C:\Windows\PolicyDefinitions\en-US</strong><br />
or<br />
<strong>\\%yourdomain.local%\SYSVOL\%yourdomain.local%\PolicyDefinitions</strong></p>
<p>Now try to open a new group policy object and in the left pane navigate to:<br />
User Configuration | Policies | Administrative Templates: Policy definitions (ADMX files) retrieved from the central store</p>
<p>You should see the new templates.</p>

<p>Hope this helps!</p>
