You should remove <CreateFolder Directory='AppTest' /> and change code to this:
<DirectoryRef Id="APPLICATIONROOTDIRECTORY"> <!-- main folder ur app -->
<Component Id="AppTest.dll" Guid="3947344C-8116-48FB-9F8A-080EA7D1ABAD">
<File Id="AppTest.dll" Source="$(sys.CURRENTDIR)files\AppTest.dll" KeyPath="yes" Checksum="yes"/>
<File Id="msvcp80.dll" Source="$(sys.CURRENTDIR)files\msvcp80.dll" />
<File Id="atl80.dll" Source="$(sys.CURRENTDIR)files\atl80.dll" />
<File Id="msvcr80.dll" Source="$(sys.CURRENTDIR)files\msvcr80.dll" />
<File Id="Microsoft.VC80.ATL.manifes" Source="$(sys.CURRENTDIR)files\Microsoft.VC80.ATL.manifest" />
<File Id="Microsoft.VC80.CRT.manifest" Source="$(sys.CURRENTDIR)files\Microsoft.VC80.CRT.manifest" />
<File Id="AppTest.inf" ReadOnly="yes" Source="$(sys.CURRENTDIR)files\AppTest.inf" />
</Component>
</DirectoryRef>
