first go to
C:\Program Files\Common Files\microsoft shared\Web Server Extensions\12\BIN

then type
stsadm –o addsolution –filename ApplicationTemplateCore.wsp

stsadm –o deploysolution –name ApplicationTemplateCore.wsp -allowgacdeployment -local

stsadm -o copyappbincontent

then go to central administration --> Operations --> Solution management

You can see your solution there(ApplicationTemplateCore).

Now you have to add your necessary templates...
Same as early

stsadm –o deploysolution –name ApplicationTemplateCore.wsp -allowgacdeployment -local

Now go to central administration with a hope !
