Why do I receive warnings about the location of the LOGICAL, ISNUMERIC, and ISLOGICAL functions in MATLAB?

When I type

ver

at the MATLAB prompt in MATLAB 7.0 (R14), I receive the following warnings:

 Warning: Builtin function logical should be found in matlab\datatypes and not in c:\matlab7\toolbox\matlab\elmat\@uint8\logical.bi

These warnings occur when installing MATLAB 7.0 (R14) into the same directory, such as "c:\matlab7", as a beta version of MATLAB 7.0 (R14).

To avoid these warnings, uninstall the previous version of MATLAB before installing the new version of MATLAB, or make sure that you are installing into a clean directory that do not contain any instances of a MATLAB installation.
