During the installation, activation, and startup of MATLAB or other MathWorks Products, the MathWorks Installer Activation Client, or MATLAB creates a log file that may be used to obtain information on the installation, activation, or startup processes. See each section for where each log is located.
Installation logs
Windows
The installation logs are in the following folder with the name "mathworks_%username%.log":
C:\Users\%username%\AppData\Local\Temp
If you are unsure how to open this folder, follow these directions:
  1. Hold the "Windows" key and press the "r" key
  2. Copy and paste the following into the Run window: %temp%\mathworks_%username%.log
  3. Press enter on your keyboard.
Linux
The installation logs are in the following folder with the name "mathworks_$USER.log":
/tmp
macOS
Follow these steps to retrieve the installer log file on a Mac:
  1. Log in as the user who ran the installer.
  2. Open Spotlight Search by clicking the magnifying glass in the top right of your screen.
  3. Type in "Terminal" and then open the first result, which should be the Terminal application.
  4. Copy and paste the following command, and then press enter/return on your keyboard. Do not edit the command, run it exactly how it appears below:
cp $TMPDIR/mathworks_$USER.log ~/Desktop
This will create a copy of the needed log file on the desktop. If the command fails, this means the installer log file is not being created. This could indicate that the installer is not starting at all, and is thus not able to write the log file.
Forcing the creation of the installation log file in a specific location
If the installer is not creating a log file, then you may need to create your own. You can run the installer in command prompt or terminal with a flag to force a log file to be created. You could use a command like the following to do this:
Windows
/full/path/to/setup.exe -outputfile "C:\path\to\logfile.log"
Linux/macOS
./install -outputfile /path/to/logfile.log
Service Host logs
There may be several Service Host log files in the folder where are located. The most recently created one (the one with the largest number in its name) is your most recent log file and will help you determine the issues are running into.
Windows
The Service Host logs are in the following folder:
C:\Users\%username%\AppData\Local\MathWorks\ServiceHost\logs
If you are unsure how to open this folder, follow these directions:
  1. Hold the "Windows" key and press the "r" key.
  2. Copy and paste the following into the Run window: C:\Users\%username%\AppData\Local\MathWorks\ServiceHost\logs
  3. Press enter on your keyboard.
  4. This will open the folder with the log files.
Linux
The Service Host logs are in the following folder:
/home/$USER/.MathWorks/ServiceHost/logs
macOS
Follow these steps to retrieve the Service Host log file:
  1. Open Finder
  2. In the top left corner of your screen, you should see buttons such as "File, Edit, View". Select "Go".
  3. Select the second-to-last option "Go to Folder..."
  4. Type in the following: ~/Library/Application Support/MathWorks/ServiceHost/logs
  5. Press enter/return on your keyboard.
  6. This will open the folder with the log files.
Activation logs
Windows
The activation logs are in the following folder with the name "aws_%username%.log":
C:\Users\%username%\AppData\Local\Temp
If you are unsure how to open this folder, follow these directions:
  1. Hold the "Windows" key and press the "r" key
  2. Copy and paste the following into the Run window: %temp%\aws_%username%.log
  3. Press enter on your keyboard.
Linux
The activation logs are in the following folder with the name aws_$USER.log":
/tmp
macOS
Follow these steps to retrieve the installer log file on a Mac:
  1. Log in as the user who ran the installer.
  2. Open Spotlight Search by clicking the magnifying glass in the top right of your screen.
  3. Type in "Terminal" and then open the first result, which should be the Terminal application.
  4. Copy and paste the following command, and then press enter/return on your keyboard. Do not edit the command, run it exactly how it appears below:
cp $TMPDIR/aws_$USER.log ~/Desktop
This will create a copy of the needed log file on the desktop. If the command fails, this means the activation log file is not being created. This could indicate that the activation client is not starting at all, and is thus not able to write the log file.

I was using the student version and the MATLAB was activated on two machines. I deactivated one and tried installing again. And it worked.

Student license can only be activated on one machine at a time, and there is a limit of about 4 times per year that they can be switched between machines. If you need to regularly run a student license on more than one machine then your options are:
  1. use MATLAB Online instead; or
  2. buy more than one license; or
  3. activate on only one machine that you own, and when you are away from it, use a program such as Go To My Pc, or Teamviewer, to connect to the one machine remotely; or
  4. if you are at a university that is providing licenses to students under the Total Academic Headcount (TAH) license, then those licenses are considered Academic licenses and are authorized to be activated on two machines at the same time

If you purchased MATLAB yourself, then Mathworks would have sent you your license number or activation key, probably through email.
If you are using a license provided by a university or company, they will have to provide the license number or activation key to you.

The volunteers who answer questions here are not able to issue licenses. You will need to purchase a licenses from Mathworks (or a distributor), or arrange a license through your university.

If you are using a license provided by a university or company, they will have to provide the license number or activation key to you.
The volunteers who answer questions here do not have access to the license database, so we cannot assist you with checking licenses.
