MATLAB: Opening a simulink file that was saved in R2018b version onto a R2017b version.

simulink matlab version r2017b

Hi guys, I have a Simulink file which was saved in the R2018B version of MATLAB, however, I only have access to the R2017B version of MATLAB. Is there any way for me to access the R2018b file? I do not have the R2018b version of MATLAB at all.

Simulink has a preference, in the Model File section, called "Do not load models created with a newer version of Simulink". You can temporarily turn this off rather than edit the model files to change version numbers.
If the model uses only basic blocks then it might be possible to load it in R2017b, but it could also crash MATLAB. As others have commented, using the "Export to Previous Version" feature is the supported way to take a model from a later release to an earlier one.
Remember to turn the preference "Do not load models created with a newer version of Simulink" back on afterwards.
