Unable to run a live script

I installed R2017a at first and it can't run live script then i unstalled R2017a and installed R2017b and it still can't run live scipt. What is wrong with my laptop or the system? Can someone please answer this? I mean that I can create or open .m file but I cannot open or create .mlx file on my matlab. Once it says i cannot use live editor on my system, but my system is just win10. most of the time when i try to open or create a live script, it just went dead.

Lu - please clarify what you mean by live script. Are you running a script (or calling a function) from the command line? Are you observing any errors? If so, what are they?

[Jan]

Explain "can't run live script" with any detail. What do you try exactly?

Hi Lu,

I have a few suggestions for you:

1. Make sure you have write access to the temporary directory that MATLAB is using. To get the path to this directory, you can execute the following command in the MATLAB command window:

>> tempdir

If the issue is related to permissions, you could also try running MATLAB as administrator and see if that lets you open live scripts.

2. Regenerate preferences for the version of MATLAB you are using. For steps on how to do this, please see this MATLAB answers post.

Restart MATLAB after making these changes and see if you can read live scripts then. If not, could you be more specific about what you mean by it 'went dead'?

Experiencing problems running Live Scripts if computer is offline. I can't even load the live script. All I get is a chromium (google chrome) -like error page with the following:

This webpage is not available

ERR_NAME_NOT_RESOLVED

The server at localhost can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Chromium from accessing the network.

I have tried to reset/flush the DNS service (running on MacOS 10.13.3) with

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

Restarted Matlab (9.1.0.441655 (R2016b)) but still go same error. As a curiosity, if I now connect through my mobile (using it as a hotspot), the Live Script magically loads. Any other form of connection or being offline does not load the Live Script.

[Pablo Blinder]

Oh... and one more thing, if you one goes offline, the Live Scripts stops running an a gray box displays the following [cryptic] message: "Message Service Fatally Disconnected".

Amy's suggestion of running as Admin worked for me! Running Windows 10 x64, and clicking "New Live Script" button just caused editor to freeze and not respond. Now fixed!

[Angelica Parente]

I'm having the same annoying issues on mac os 10.13.3, seemingly randomly matlab will freak out and multiple "message service fatally disconnected" popup messages will show up. Also this seems like a separate issue, but sometimes when I try to open the Color window to change the color of a plot, it takes a very long time to load and eventually the Color window just says "This webpage is not available ERR_NAME_NOT_RESOLVED:"

This has happened both with and without livescripts running. Wondering if its related to google drive somehow?

[Zhaojie Yao]

I have the same problem, trying to create or read any live scripts

"This webpage is not available ERR_NAME_NOT_RESOLVED:"

[Andy Meyers]

Resolved this problem. My localhost wouldn't ping on my mac, which was part of the issue.

[Adriana Salguero]

Please can you tell me how you fixed the problem?
