Cubase artist fails to launch

Hello,

I purchased a license for the Cubase Artist 15 DAW. After a successful installation, the program fails to launch and reports an unsupported processor type. Please suggest a solution to this problem. I intend to use the DAW for standard audio recording editing.

Thank you.

Processor is

Intel Core i5-10400F Comet Lake Processor

In that case, the Intel Core i5-10400F Comet Lake processor is the ideal choice with regard to flawless operating conditions and high stability under load. Of course, a whole range of supported technologies, including WiFi 6 or Thunderbolt 3, is also available.

6 cores

Number of processor cores

System requirements for Steinberg products

Hi.@Alfo,
unless I am missing your point, @veselka_vlastimil’s CPU meets C15’s system requirements…

People buy things without first finding out whether what they are purchasing is actually suitable for their purpose. That is the problem that creates new problems.

But @Alfo, you don’t know that that’s the case here – in fact the OP’s system does exceed the minimum requirement, as @Reco29 points out.


One of the things that makes this forum useful is that participants provide correct and helpful info, your posts would be better if you made sure that the answers you give are relevant to the issue at hand and correct.

Hi @veselka_vlastimil and welcome to the forum!

Back to your problem: As you know by now, your CPU should do. Usually, HT shouldn’t cause any trouble with Cubase when ASIO Guard is turned on (it is per default). Nonetheless, can you temporarily disable HT and try to launch Cubase? Just to narrow down potential causes.

What kind of audiointerfaces & ASIO driver do you use? Same question with regard to GPU.

Yes. Thank you. Maybe my computer wasn´t updated. It
looks likes thé computer Is already working.

Just for clarification: Does C15 launch as expected or doesn’t it…?
Did you update your BIOS and other system components?
