Issues with Cubase AI 12

I received an email from Steinberg that I could get a free update to Cubase AI 12. I have been enjoying Cubase AI 11 for some time and I thought that I would have the same experience with AI 12. From the time I downloaded and installed Cubase AI 12, it never worked for me. I opened projects that had been created on Cubase AI 11 but now running AI 12. I encountered several issues. I could not import audio files (wav and mp3). Received error messages “Cannot convert this type of file” “Could not create record file”. Attempts to export the Audio Mixdown failed repeatedly. Nothing happened when I tried to export to mp3 files. Error message during attempt to export to wav file was “Unexpected error.”
I thought reinstalling AI 12 would help, but it made no difference. I received the same error messages. I am beginning to feel that there is a bug in Cubase AI 12 that the developers are not aware of. I am running Windows 10 on my PC.

Can a Steinberg representative please advise me what the solution to the problems with Cubase AI 12 is? Or does anyone else on the Forum have a clue as to what is going on? I would appreciate any advice. Thanks.

Hi and welcome to the forum,

Try to reinstall Cubase 12. Make sure, you install it as administrator, please.

Thank you Martin. I will try the solution you recommended. Hopefully it will work.

Martin, Yes I tried again to reinstall as you suggested. Even after reinstallation of Cubase AI 12 as administrator, it refused to work. This is truly frustrating. Is there another solution out there please?

Hi and welcome to the forum,

Can you see any DMP file in the Documents/Steinberg/Crash Dumps/ folder? Can you attach it/them, please?

Martin, I ran Cubase AI 12 again, and it still won’t work properly. So I did what you suggested and looked for the DMP file as you said. The latest DMP file listed was from Mar 7th 2021 so it could not be from running AI 12. There is no DMP file from recent days. Any clue as to what is happening?


Generate a DMP file and share it via Dropbox or similar service, please.

Use Microsoft ProcDump utility to generate a DMP file, please.

  1. Please download ProcDump64 from Microsoft (~650kB) and extract the archive to a local folder on your harddisk.

  2. Run Command Prompt (cmd) as administrator (right click and select “run as administrator”)

  3. Navigate (in the Command Prompt) to the folder with the extracted procdump file.
    For example:
    cd C:\ Users \ \ Downloads \ Procdump
    Note: the dmp file will be written into that folder.

  4. Launch Cubase/Nuendo. You can work as usual. At any time, change to the command prompt and start procdump, to monitor Cubase/Nuendo for unexpected behavior (see next step).

  5. Launch procdump64 via Command Prompt:
    Cubase 12:
    procdump64 -e -h -t Cubase12

Nuendo 11:
procdump64 -e -h -t Nuendo11

The -h option will write a dmp file in case of an application hang. This might kick in too early sometimes, in case some action takes a little longer. Feel free to skip the “-h” option, if you are only up for fetching crashes.
The option -e will catch exeptions and the option -t terminations of the application.

  1. Prodump is now monitoring the Cubase/Nuendo process and will write a crash log, in case Cubase/Nuendo crashes or hangs. Perform the action that causes Cubase/Nuendo to crash and send us the generated crash dmp.

ZIP and share the DMP file via Dropbox or similar service, please.
