I'm a Luddite, on Windows 7, so WIndows 10 is a "known unknown"
Anyway, if it works on UBuntu, it will work on Windows 10.
Have a look in the "Instruments" and Samples" sub-folders. Start with those "SE" instruments, the ones that do work. For each instrument you should see a .st4i file in a sub-folder in "Instruments" and a similarly-named .pak file in a sub-folder in "Samples".
I think that the installation of the ST4 software installs all the instrument files (.st4i) too. But the associated .pak files are installed separately.
You may need to turn off "Hide extensions for known file types" in Explorer / Tools / Folder Options / View.

Ah, hold on a moment - did you download the ST4 SOunds Library files or were they on a USB drive? If the latter:
Peter - IK Multimedia, some time ago wrote:Bruceferraudi wrote:So doing a fresh ST4 Max USB install on a new computer and I haven't installed my prior copy of ST3 yet. How would I best going about doing this, what sequence should I follow from the USB version?
Register your SampleTank 4 serial number first. Then, I would recommend downloading and installing the 4.0.3 latest version from your IK User Area first followed by Instruments Installer 1.1. You can then skip the application installer on your USB stick.
Then, you can run the sound library installers from your USB stick to install all the sounds (there should be a SampleTank 4 sound library installer and a SampleTank 3 sound library installer, run each of those).
Next, download the additional pianos available in your IK User Area (these are the additional files that would not fit on the USB stick):
Additional Piano Instruments
Additional Piano Samples Part 1
Additional Piano Samples Part 2
Additional Piano Samples Part 3
Additional Piano Samples Part 4
Additional Piano Samples Part 5
Additional Piano Samples Part 6
Additional Piano Samples Part 7
Additional Piano Samples Part 8
Additional Piano Samples Part 9
Additional Piano Samples Part 10
Finally, download the latest sound updater (1.3) from your IK User Area and run that.
