Simulink does not show DSP Builder menu

Hello,

I meant that DSP Builder library is not displayed in Simulink Library Browser:

Is Matlab R2015a compatible with DSP Builder 22.4? Apparently it should be compatible according to DSP Builder Installing wizard.

After executing "DSP Builder - Start in MATLAB R2015a" (or "DSP Builder - Start in MATLAB R2022a") Matlab path is changed to "C:\intelFPGA_pro\22.4\quartus\dsp_builder". However, this directory is empty. All simulink files seem to be in "C:\intelFPGA_pro\22.4\quartus\dsbab". According to the thread https://community.intel.com/t5/FPGA-Intellectual-Property/DSP-Builder-Installation-Problem/m-p/69978, dsp_builder path should include BlockInfo.dll. Could this be the problem?
