Question
while try running the Uav simple flight model the following errors occours Windows cannot find 'C/Program'.Make sure you typed the name correctly, and then try again. and this below appear in the Matlab diagnostic viewer MATLAB System block 'uav_simple_flight_model/Simulation 3D Scene Configuration/Simulation 3D Engine' error occurred when invoking 'resetImpl' method of 'Simulation3DEngine'. The error was thrown from ' 'C:\Program Files\MATLAB\R2020b\toolbox\shared\sim3d\sim3d\+sim3d\EngineInterface.p' at line 0 'C:\Program Files\MATLAB\R2020b\toolbox\shared\sim3d\sim3d\+sim3d\Engine.p' at line 0 'C:\Program Files\MATLAB\R2020b\toolbox\shared\sim3d\sim3d\+sim3d\Project.p' at line 0 'C:\Program Files\MATLAB\R2020b\toolbox\shared\sim3dblks\sim3dblks\Simulation3DEngine.p' at line 0'. Caused by: 3D simulation engine interface setup error. How do i fix this issues? Any help will/would be appreciated. Thanks.

This issue is potentially caused by spaces in the Windows "%temp%" directory path. Once your Windows "%temp%" directory path does not have a space, the simulation should be able to execute without error. Spaces in the Windows "%temp%" directory may be caused by spaces in the Windows username.
Here "C:\Program Files\" seems to contain a space character. Changing to a directory without the "space character" in the path might help resolve this issue.
