I had Nahimic for Msi and its music section didnt work. Then i thought that there should be an uptdate for my app and i found the update file. I updated realtek to 6.0.1 then started the update nahimic 2.3.4 and it reported me that the installation has failed. Then i looked this site for my problem and saw this link
i thought maybe that kind of a problem is my update problem. I ve done this steps and installed realtek again. Then i started nahimic 2.3.4 installation again and I am still taking this problem.
