There is actually a method that is much easier and doesn't require any additional 
software.
The TFW (world file) cantains onlt 6 lines of information

pixel x size    =  a
rotation (always 0)
skew (always 0)
pixel y size (negative number unless in the southern hemisphere) = b
upper left x co-ordinate = c
upper left y co-ordinate = d

Knowing these details and the projection of the raster it is very easy to register 
this in mapinfo:

1) Open the raster and select "Register"
2) Select proper coordinate system and units
3) Select any point and fill in the following values
Map x:  c
Map y:  d
Image x: 0
Image y: 0
4) Select a new point and fill in the following values
Map x:  c + a
Map y:  d
Image x: 1
Image y: 0
5) Select a new point and fill in the following values
Map x:  c + a
Map y:  d + b
Image x: 1
Image y: 1
6) Select a new point and fill in the following values
Map x:  c
Map y:  d + b
Image x: 0
Image y: 1
7) Click "OK" and you are done!
Simple, eh?
