Version 2018b 64-bit on Windows 10, only MATLAB 9.5 installed (no add-ons). I have tried reinstalling the program and resetting to the default path but none of those have worked. I have tried searching around on the web but it seems as though barely anyone else has this issue. Please let me know what other info I should provide to solve this issue.

Try again with administrator privileges when installing Matlab.
Or, if there is the same version of Matlab installed on Windows 7 etc., the error will not occur if you copy and save the missing file in the Help folder from the old PC.
The following five types of files and folders are missing (in the case of the Japanese version):

I got this problem after removing MATLAB 2019b and reinstalling it ... the original problem had been ...
Caught "std::exception" Exception message is:
Bundle#315 start failed: Loading C:\Program Files\MATLAB\R2019b\bin\win64\builtins\sl_graphical_classes\mwsl_graphical_classes_builtinimpl.dllfailed with error: %1 is not a valid Win32 application.
after reinstalling, this went away and now I'm getting:
Caught throwable while adding doc set item to doc set builder: null
Caught throwable while adding doc set item to doc set builder: null
So far, I can see what harm this is doing .. but it would be nice to know.
