Excellent sound mod and i had problems getting this installed so im gonna make a little step by step tutorial.
1. Download the mod from this page and then drag the file on to your desktop.
2. open the file with 7 zip and click on lets say the msf_williams_fw26_late and click on the file and on sfx and then you will find 2 files.
3. You will se one that says msf_2004_williams_fw26_late.bank and the other one will say GUIDs.txt.
4. open your assetto corsa folden and go to content/cars/msf_williams_fw26_Vers_B_sfx There you will find 2 folders. Those 2 folder, delete them. (or backup them if you want)
5. Mark the 2 files from 7 zip and then simply drag them into the sfx folder.
6. and if you now go into CM/ assetto corsa you will find it still not working!
7. In the sfx file rename the msf_2004_williams_fw26_late.bank to msf_williams_fw26_Vers_B.bank. And then double click on the GUIDs.txt file and open it with notepad then click Control + H on your keyboard.
8. A little box sould pop up and in the box search for type in msf_williams_fw26_late. In the box under that says: raplace with. In that box type in msf_williams_fw26_Vers_B and then click on the obx that says: Replace all.
9. You can click on the X or cross to close the box and then click on archives and then on save. after that close the tab and then boot up Content manager and it should work!
With the other version just do the same but without the _Vers_B
just rename it msf_williams_fw26 :) I hope this did help a few people so enjoy the scream v10!
