As a general guidance, you may read our article
RAID Recovery Presentation.
More details is in our on-line and program help:
Volume Sets and RAIDs
And if you need to find the RAID parameters, like an offset, block size and order, etc, the article
Finding RAID parameters may be of some help.

My original configuration was a windows raid 5 (desktop pc, no raid controllers, no scsi drive), just a simple plain desktop with 4 ide's of which one failed.
So my question still stands - with my original configuration being a windows raid 5 (original 4 drives) - now I'm running with 3 drives and now one of those failed - am I telling r-studio to set my virtual-raid as a stripe, to recover what was placed on the 3 drives, or, do I need to create a raid 5 system.
A RAID5 5 virtual RAID. 4 or 3 disks, that is the question. If your Windows (quietly for you) had rebuild the layout from 4 disks to 3 disks, it should be a 3 disk system, if not, a 4 disk one. And this is the most difficult task to solve. It's even more difficult to do remotely without browsing thoroughly through the data.

Of a "missing disk" object. See our help for more details.
So, I'd do the following:
First, I'd try the 4 disk layout, than, a 3 disk one.
And please do understand the following: data recovery is similar to, say, car repairing. An ordinary driver can check gas level and tire pressure. Probably, change a flat wheel. A properly qualified mechanic can do much more. Your case is close to, say, an engine overhaul. Had it not been the lost 4-th disk, it would've reduced to an adding some engine oil when its level is low.
R-Studio is merely a tool. A very good tool, as many say, but still a tool that require a proper qualification.
