Cubase 12 can't start

Please help i have a problem Can’t access Cubase12, it has access to the vst mixer. I am using windows


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 12:
procdump64 -e -h -t Nuendo12

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.

Why is it so complicated? So how do I fix the problem?
Please tell me something easy.

Then start it in safe mode and see if it loads


The process I described above has nothing to do with Cubase. This is Windows procedure.

Hard to guess, if we don’t know, what is really crashing.

Could you try in the Cubase Safe Start Mode [Disable preferences], please?

How do we solve this problem?

I have cleaned my computer and reinstalled Windows 10. Previously, this problem could not be resolved. Now encountering a new problem with HALION SONIC SE3, please help.


Make sure, you have the latest version of HALion Sonic SE and the library installed. You can do so from the Steinberg Download Assistant.

yes, i has already been installed.


Does the sound come from any official library?

Please tell me how.
