After installation of documentation on the PC, I get "Invalid default value for property 'Location' in class 'matlab.in​ternal.doc​.url.DocPa​geParser'"

How can I mitigate that ?

@Mathieu GRISON Can you provide the exact reproduction steps leading to the error?

Thanks for looking at my issue !

Activation and installation went well (R2024b update1) except :

I get "unrecognized function or variable "settings"

I used forum solution :

>> restoredefaultpath

>> rehash toolboxcache

>> savepath

Then after installation : preferences / help / Documentation Location to ask for installation offline of help.

it looked to go well, but anything I ask in help little windows leads to :

(while I am writing) :

Error using weboptions (line 378)

Unsupported input: string

Error in matlab.internal.doc.search.sendSearchMessage (line 13)

options = weboptions('RequestMethod','post', ...

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Error in matlab.internal.doc.search.configureSearchServer (line 13)

matlab.internal.doc.search.sendSearchMessage('addons', 'Body', '[]');

(and when I hit enter)

@Mathieu GRISON,

To verify that MATLAB opens the locally installed documentation, restart MATLAB after installing the documentation, and enter this command in the MATLAB Command prompt:

doc

On the documentation home page that opens, if the URL points to a local IP address and port number (for example, http://127.0.0.1:12345), then MATLAB is accessing the locally installed documentation. Providing this output could help in debugging the issue.

Also, could you elaborate on how the help command was used? Perhaps for a specific function? Are you writing it in the command window?

Hi @Mathieu GRISON,

I was able to install documentation offline in MATLAB R2024b Update 1 without any issues, following the steps mentioned in the following documentation:

https://www.mathworks.com/help/install/ug/install-documentation-using-internet-connection.html#mw_930ce40c-7fb8-478a-a333-4b6440310378

I would suggest performing a reinstall of MATLAB and following the steps mentioned in the above link to install documentation offline. If the issue persists, consider contacting MathWorks technical support here:

Hope this helps!

Many thanks for these propositions.

I was unable ton accept the response for an unknown reason, now it seems to work properly.

I initially thought it was sufficient to select "Preference / Help / Documentation Location and choose "local" since it leaded to download data, and no faillure message appeared. But ... no.

Now I see that I can try an offline installation of documentation and I will try that and read the docummentation you mentionned as soon as I can (too busy right now). All the more since I know for sure that the installation of matlab itself must be done with the offline way in my company. I will let you know.

Cheers
