How do I resolve a MATLAB installer fail with an error related to a lxe_win64 or .enc file?

When installing MATLAB on my machine I get an error similar to the following example:

The following error was detected while installing lxe_win64:

Missing Entry: lxe_win64_1368859906.enc

OR

Missing Entry: lxe_common_1384906630.enc

Would you like to retry installing lxe_win64/lxe_common? If you press NO, the installer will exit without completing the installation. More information can be found at C:\Users\<user_name>\AppData\Local\Temp\mathworks_<user_name>.log

Try one or more of the following steps to resolve the issue:

• This error can be caused by an anti-virus or security program interfering with the MATLAB installer. Disable any anti-virus you have running, and then rerun the installer.
• There may be an issue with the target installation directory. Rerun the installer and specify a new directory that did not previously exist on the system.

Note: Remove the folder in the following path as well: C:\Users\<username>\AppData\Local\MathWorks\MATLAB\R20XXx

• If you installed a prerelease of MATLAB, remove the existing prerelease installation. Then, rerun the installer.
• If you are installing R2018a or older, the files that you downloaded may be corrupt or incomplete. Delete the installation files on your system. Then, download your products again and rerun the installer.

Removing the previous directory solved it for me :)

You need to contact Mathworks Support. The volunteers who answer questions here do not have access to the download infrastructure, so we cannot look at the internal logs to see what might be happening.

[Michael Valasek]

To switch off anti-virus is a joke?

I cannot install Matlab after 8 hours of work. Horrible design of installation. Whay is it not done in separate parts? Why is it necessary to start from scratch?

Very unsatisfied.

I don't know if it's actually the way to solve this, but after three times with this error I decided not to install the communication toolbox and it worked, matlab is already installed.

[zhentao Zhang]

same problem how to solve it

[Colin Fraser]

We did recently release a new MATLAB Update with the installer that might resolve some of these issues. It would be worth trying to download the installer again and attempting.

I am having the same problem. How do you install using another directory?

[Hamdan Nuruddin]

I had the same error message as above. My computer hang while running the installer

[Rini Akmeliawati]

Clean up your directories from old or unsuccessful installation of MATLAB. You can do so by uninstall the old MATLAB, then clean up all the paths related to it. Then re-install your new MATLAB.

[Sara Siniscalchi Minna]

I have experienced same issue and I am not able to find a working solutions. Could anybody help?

Answer 9

[Carlos Orduno]

I tried all the other options and none of those fixed my issue, and installing it into a new directory fixed the issue. I just added a 2 at the end of the proposed directory.

this is the issue that I had.

m3i_core_win64_1574376026.enc

m3i_core_win64

another step that I made, but I'm not sure if that helped, I installed just matlab and simulink first, after it was completed and activated, I installed the rest of the packages.

UPDATE: I just had a similar issue while updating Matlab on my Mac.

m3i_core_maci64_1574371482, m3i_core_maci64

this is what I did, I deleted the folder from Applications and installed first Matlab and Simulink, that avoided the extract error.

[Colin Fraser]

Hi,

If you are still experiencing this issue, please contact MathWorks support:

http://www.mathworks.com/support/contact_us/

-Colin Fraser

[Walter Roberson]

It is strange that a Windows system would want to download a Mac-specific file, m3i_core_maci64.*

When I look through the R2019b installation, it appears that you might be able work around that file being missing by not installing the toolboxes that depend upon it. If you do that, you could at least proceed with the installation, and then come back later to try to do the others, perhaps one at a time.

The toolboxes that want m3i_core* appear to be:

• Antenna Toolbox
• Bioinformations Toolbox
• Deep Learning Toolbox
• Fixed-Point Designer
• Image Processing Toolbox
• MATLAB Coder
• MATLAB Report Generator
• RF Toolbox
• Signal Processing TOolbox
• SimBiology
• Simulink
• Stateflow
• Symbolic Math
• Wavelet

I would suggest turning off installing those for the moment, getting everything else installed, and then going back to try to install Simulink.

Hi, when installing MATLAB on my machine I get an error like the following:

Would you like to retry downloading 3p/eclipsexbaseruntimelibrary_common_1563491806.enc? If you press No, the installer will exit without completing the installation.

YES OR NO "
