"Please install MDK-ARM V5.32 toolchain to open the project" but Keil 5 already installed

[Quizark]

When generating code with stm32cubemx, an interface pops up, saying that I don't have the MDK-ARM toolchain installed, but I can burn the code normally with keil5 on my computer, why is this?  what can I do next?

Well, that's only one of the things it suggests.

The other is that you need to "associate the file type of the project with your Toolchain..." - so have you done that?

[Quizark]

Yes, it's the only way, but I don't know how  to associate the file type of the project with my Toolchain.

If you look in that folder using the Windows File Explorer, what does it say the 'Type' is for the generated project file?

Can you open it just by double-clicking?

[Quizark]

That's the state when you open it
This is my own folder, the first and second are for calling the HAL library and using the project files written directly in keil5 respectively
The third is the downloaded java runtime
The fourth one is the installer of the stm32cubemx that I downloaded
The fifth one is the installer that I downloaded keil5

You haven't shown the project file.

Is this one？This is something that is automatically generated in the folder after I click on the generated code.
