Hi hjhjhj
Uninstalling the v1.0.0 should be enough. Nevertheless, in order to be absolutely sure this is what i would do:
Step1: remove all the other toolboxes from Matlab path: see this post how to do it https://community.nxp.com/thread/449904#comment-908457
Step2: Restart Matlab and go to {Install path}\MBDToolbox\mbdtbx_MPC574xP\
Step3: run the mbd_pnt_path.m to set again the correct paths for v2.0.0 into Matlab
After these steps you should have the SIL/PIL running correctly for v2.0.0 toolbox
Hope this will resolve your issues
Best regards,
Daniel
