How do I resolve a MATLAB installer fail with an error related to a lxe_win64 or .enc file?

When installing MATLAB on my machine I get an error similar to the following example:

The following error was detected while installing lxe_win64:

Missing Entry: lxe_win64_1368859906.enc

OR

Missing Entry: lxe_common_1384906630.enc

Would you like to retry installing lxe_win64/lxe_common? If you press NO, the installer will exit without completing the installation. More information can be found at C:\Users\<user_name>\AppData\Local\Temp\mathworks_<user_name>.log

Try one or more of the following steps to resolve the issue:

• This error can be caused by an anti-virus or security program interfering with the MATLAB installer. For more information regarding potential anti-virus issues, see the following article:

• There may be an issue with the target installation directory. Rerun the installer and specify a new directory that did not previously exist on the system.

Note: Remove the folder in the following path as well: C:\Users\<username>\AppData\Local\MathWorks\MATLAB\R20XXx

• If you installed a prerelease of MATLAB, remove the existing prerelease installation. Then, rerun the installer.

• If you are installing R2018a or older, the files that you downloaded may be corrupt or incomplete. Delete the installation files on your system. Then, download your products again and rerun the installer.
