I just installed R2020b using a site license from my university; previously I had a standalone license. When I start it up, I get a slew of errors:

Warning: Name is nonexistent or not a directory: C:\Program Files\MATLAB\R2020b\toolbox\shared\matlab_datatypes

This is under Win10 Enterprise. My ver output is this:

-----------------------------------------------------------------------------------------------------

MATLAB Version: 9.9.0.1467703 (R2020b)

MATLAB License Number: <removed>

Operating System: Microsoft Windows 10 Enterprise Version 10.0 (Build 19041)

Java Version: Java 1.8.0_202-b08 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode

-----------------------------------------------------------------------------------------------------

MATLAB Version 9.9 (R2020b)

Deep Learning Toolbox Version 14.1 (R2020b)

Optimization Toolbox Version 9.0 (R2020b)

Signal Processing Toolbox Version 8.5 (R2020b)

Wavelet Toolbox Version 5.5 (R2020b)

Do I need to worry about these messages? Also, I think I asked for more toolboxes/products when I did the installation, including at least the mapping toolbox, MATLAB Compiler, and maybe MATLAB Coder. The toolboxes shown above are the ones I had in my standalone installation of R2019b. Any suggestions? Thanks.
