right i'll take you through the manual install process then... seems it might be easier

you will need to show all files on the amiga side, you can do this by pressing down the right mouse button to get the menu up, and goto window and then show, all files...
heres the step by step guide:
1. copy everything from the c directory to your C: directory (in your workbench partition (show all files) c)
2. copy PC2AmParallel.device from the devs directory to your Devs: (found in workbench:devs/)
3. copy everything from l to your l directory (again workbench show all l)
4. copy the igs.library from the libs directory to your libs: (workbench:libs/)
5. right now ive gone to the liberty of doing this bit for you (configuring it) ive assumed your using a standard parallel laplink cable so copy
this file and
this one to somewhere, make sure you put them both in the same place the PC.info file is the con for the PC file...
that should be it... now run the program on the PC then double click on the PC file you downloaded from me... and you should get a PC icon appear on your workbench, open it (double click) and you should hopefully see your windows drives there (all labelled C,D etc)
