After moving to a new System drive and re-installing Dorico Pro 3.5.12, I just now downloaded the Dorico sounds installer via Steinberg Download Assistant and ran it.
When I opened the “Dorico Prelude” sample score, I got the message “Cannot located Impulse Response File: LA Studio.wav”.
Again, I just downloaded this a few minutes ago. And I ran the installer three times.
Would someone from Steinberg please send a link to the file - from the similar threads here, it seems that’s the only option.
Now that I think of it, I’ve probably gotten that message a lot on my old system drive; I just ignored it.
Also, please make the text in the error message box selectable so we can copy and paste when reporting issues. (It’s possible in other apps, like MOTU Digital Performer.)
