and then
CreateDirectory "$SMPROGRAMS\Alykel"
CreateShortCut "$SMPROGRAMS\Alykel\..."
or :
RMDir /r "$INSTDIR"
RMDir /r "$SMPROGRAMS\Alykel"
Something says me that second example will be more correct ;-)
Delete "$INSTDIR\.."
Delete "$INSTDIR\.."
RMDir "$INSTDIR"
SetShellVarContext all
Delete "$SMPROGRAMS\Alykel\.."
Delete "$SMPROGRAMS\Alykel\.."
RMDir "$SMPROGRAMS\Alykel"
