Vista - International Rally Championship - Windows 95 Only

Hello! I have try to install and play the old game International Rally Championship. My problem is that the game is for Windows 95 only, and there I haven't been able to install it on the Vista.
I have found a patch for the installation, but I have some problems getting the patch to work. Link to the patch: rcpatch6.zip - FileFront.com
Here is a selection of the guide to us the patch:

As you cannot install the game using the exe on the CD, you will need
to ensure that the current directory do the following to install the game.

1. unzip the patch to your hard disk eg C:\PATCH
2. open a dos prompt box
3. change directory to the Rally CD eg D:
4. run the new exe eg C:\PATCH\RAL.EXE
5. install the game
NOTE: Immediately after installation the game is run, this will be the
old exe that will stop with the original error message. Click OK and
continue to step 6.
6. copy the new ral.exe over the one just installed
7. run the new exe from the hard disk

Alternatively, another way is to unzip the patch as normal and create
a shortcut to the new exe ensuring that the 'target' is the new exe
and the 'start in' directory points to the Rally Championship CD

NOTE. You will not be able to autorun the Rally CD to run the game.

I have completed the two first steps, but then at step three i **** up. My CD-ROM drive is called E: on my computer, and I have just tried to type E: in the commando prompt, which actually changes it to E:, however I am not sure if that's the right way to do it.
But when I move on to point four, it still says that it can't find the International Rally CD-ROM. I have also tried the alternative method, but it still says that it can't find the International Rally CD-ROM.

Can anyone help me, and what have I done wrong?
