Sounds to me like you have everything, but have just not installed it due to limited space. Right?
If so, that should be an easy fix. Last I checked hard drive space was cheap. So as long as you are not on a laptop drop a hundred bucks and get a large, fast and cheap drive and add it to you machine. That is the way a lot of us have solved this problem.
Could it be that simple?
If only.

In another thread I posted a couple of weeks ago when I was figuring out how to accomplish my minimal
installation, I revealed I am extremely sensitive to EMF's.
Adding a second SSD is out of the question, as I would feel tension in my head.
When I bought my current SSD a few years ago (my first SATA drive) I was very happy to discover I could live with my 500G SSD. That was a big jump from my previous 160G hard drive.
When it worked I loaded up and bought 8 more of these 500G drives. I didn't think I'd be able to use them simultaneously, but at least I could back up my main SSD drive and also have spares in case my main crashed.
I have yet to try out a 1T SSD by the same company (Samsung). It might work, it might not.
One thing is for sure, it would be a huge investment in time just to get a new larger SSD set up to same state my current one is in, just for the sake of a BIAB fix.
Is there no other way to get stylepicker to work for me?
I should add one more thing. When I was doing my installation, to save space on c: I installed the program and Realtracks/Drums to d: drive (a partition of my SSD). So both c: and d: are limited in space.
