I don't use ISIS very much, as I find it is "tuned" primarily for the Shelyak instruments...(I have asked Christian to make it more "general" and suitable for first time users of "non Shelyak" instruments - he said no.)
If you're using any other spectroscope...the only way I see of using it is to determine the dispersion of your instrument and then enter this value in the "General" tab.
You could try John's "BASS project" which runs well under win8 and does all the processing you need.

This is the software I currently use for my Nova Cen ARAS submissions.
Hope this helps.
