Trouble with connecting MATLAB to AWG70002A

I am currently trying to create direct synthesis signals using MATLAB and AWG70002A. The MATLAB is installed in the AWG and I want to communicate via the virtual GPIB. I am following this AWG70k example: https://forum.tek.com/viewtopic.php?t=138015
with the following changes:
visa_vendor = 'tek';
visa_address = 'GPIB8::1::INSTR';

 I tried running the code in matlab. However, when running the visa command, I run into an error:
'Unable to create VISA object. The required drivers may not be installed properly.'
I tried to fix it by reinstalling the drivers, but the problem persists. Any help with troubleshooting is appreciated.
