Hi, Mario... I do not see on that page where it says "this will work with the free version of MSoundFactory" (or the "Player").
It shows (at the top) "Instruments for MSoundFactoryPlayer".
There are 3 versions of the MSoundFactoryPlayer - Full, LE, and Player.
https://www.meldaproduction.com/MSoundFactoryPlayerLike Kontact. If you do not have the full version (of Kontact), there are a lot of free instruments that you cannot use...

My mistake. I read player and being a Kontakt user I thought player would be the free version. It is a really confusing as all three versions are called player.
I'm going to load it up on my Internet computer, not my music computer, and see what happens when the player turns into the free player.
{edit} I just installed this onto my Internet computer. This is my impression of this software. Others may not agree.
Problem #1 - The installer is an installer for all of their software packages. There is no MSoundFactoryPlayer listed. I clicked on the little house just to the right of MSoundFactory and it took me to the web site that shows the DL windows of MSoundFactoryPlayer. So I installed it.
Problem #2 - The MSoundFactory is a demo that contains a very limited number of sounds. I opened BiaB and added the MSoundFactory VST.
Problem #3 - Well not really a problem but I auditioned a number of sounds using BiaB.
I was not impressed with any of the included sounds. There was a number of options and effects one could play with but again I was not impressed, especially considering this is a demo for a $300 product.
Bottom line was I deleted it from my computer. I have much better sounds in Kontakt, FM8, Korgs M1 and Wavestation, etc, than what MSoundFactory demoed. YMMV
