Why I receive these warning messages? Could you give me a hand, please?

I receive these warning messages after installing MATLAB R2015b. Do these problems arise because I install MATLAB file in D drive or because I already installed another version of MATLAB before?

Warning: Function loglog has the same name as a MATLAB builtin. We suggest you rename the function to avoid a potential name conflict.

Also, whenever I click any button (e.g., clicking "set path", or clicking "close"), I receive this message as below.

(Error in pathtool (line 11) error(javachk('swing', mfilename));

Attempt to execute SCRIPT builtin as a function: D:\\toolbox\matlab\lang\builtin.m

I would appreciate it if anyone answers to my question :) Thank you for reading.

Looks to me like you probably installed into the same root path as the previous installation. I'd probably uninstall and then re-install making sure to not use a prior location but one specifically for R2015b. Matlab historically has "played nice" with previous installations so this surely looks like operator error here to me.

Official support is available for installation/startup issues so if you're overly concerned about the uninstall wiping out something critical from a previous install, contact them at www.mathworks.com or simply install again making sure to use a new directory as noted above.

What operating system are you using? It looks like you have a version installed to D:\\toolbox\matlab - not sure why there are two slashes after the colon though. I agree with dpb that you should uninstall everything. If you're using Windows, then do it from the control panel "Programs and Features" icon. Then edit your path environment variable to see if it mentions any MATLAB folders. What might be happening is that some old version of MATLAB is on the search path so it finds it. If it does contain any MATLAB folders still (after uninstall), get rid of them and save the new path. Then reinstall.

You might also look at the command "restoredefaultpath".

Thank you very much for your comment! I really appreciate it. I am using Windows. To get rid of any MATLAB folders and to install new MATLAB again would be the best way to solve this problem, as you said. However, I am little concerned about wiping out the previous version of MATLAB... If it is the best solution, I have no choice but to do that.

[Image Analyst]

Then try restoredefaultpath first - that's really easy.

If that doesn't work, examine your PATH environment variable (if you're using Windows) and make sure only one version of MATLAB is listed there among all the folders.

Do one thing, delete all the saved m files which are shown under the current folder

[Image Analyst]

Why would you say that? If their current folder contains their custom-written m-files, then your "Answer" would delete everything that they have written. Not a good thing to suggest.
