Ok, when step 1. completed it would have made a new folder. I will assume you did not change the name of this folder.
For step 2, part a.
If you are using Windows XP, go to 'Control Panel' (open it). Select 'System' (open it). Look for the 'Advanced' tab (select it). At the bottom is a button that says 'Environment Variables' (click on this). In the window that appears, you should see an entry for 'PATH'. Select this entry. Click on the 'Edit' button. Do not overwrite the text in here. What you want to do is to go to the end of the text in 'Variable value:'. Add this string without the quotes ";C:\Borland\BCC55\Bin" to the end of the PATH variable.
Note: There may be a 'Path' variable not a 'PATH', or even both 'Path' and 'PATH'. If you only have one, add it to the one. If you have two, add it to the one in the 'System variable' box/area.
If you are using windows 98, you can add to the path variable in the autoexec.bat file. This is usually located in the c: drive, and not in any folder You will need to right click (with your mouse) on the file and select 'edit' to be able to open it in a text editor. Add this string without the quotes ";C:\Borland\BCC55\Bin" to the end of the PATH variable. Ie, it usually says path=something;something\else;etc
For step 2, part b.
Create a new text file and rename it bcc32.cfg
To edit this file, right click (with your mouse) on the file (after selecting it). Then select 'edit'.
In this file you will need to add the lines mentioned.
For step 2 part c.
Create another text file and rename it 'ilink32.cfg'
Open it to edit as in the part b.
Add the lines mentioned.
Then, you will need to open a MS-DOS or Command Prompt box, if you use win98 or winXP, respectively. It is usually situated in Start -> All Programs -> Accessories
After opening the MS-DOS or Command Prompt, type in 'bcc32 -?" without the quotes into the command prompt. If all the above steps are successful, you will see a help message displayed.
Good luck.
[update] ps, you will need to add (create) those files in the 'C:\Borland\BCC55\Bin' folder / directory.
