Help window doesn't appear

Hi,

when I try to open the Help Browser in MATLAB, the window does not show any content. I deinstalled MATLAB and installed it again, but the help window is still empty. I am using MATLAB R2019a Update 1.

Please help me to get help.

Best Regards

Dennis

This is a problem in the preferences folder. See https://www.mathworks.com/matlabcentral/answers/453269-create-a-backup-of-your-preferences-folder

So restoring the preferences files from the backup would solve the problem.

There is a direct solution also: Right click on the invisible Help window in the state you have recorded the screenshot in. Then choose "Maximize" and the window whould be re-appear again.

More specifically, the problem lies in the following file:

%userprofile%\AppData\Roaming\MathWorks\MATLAB\R2019a\MATLABDesktop.xml

I suggest deleting the XML <group>....</group> tag with property Title="Help"

Be sure to englobe the closing tag or else you will corrupt the file. At home this tag spans 38 lines.

Matlab will regenerate this tag with the default properties.
