I have tried loading the 8.5.20_update_win on my computer with a valid working Cubase Pro 8.5.15 and get an error which states I am missing the Cubase85_64bit.msi file (or something like this). I am running Windows 7. What am I doing wrong?
Update! I have been able to successfully load 8.5.20 by running the 8.5.15 update file again and then the 8.5.20.
