How to uninstall an older version of Matlab

Hi, I have both R2014b and R2015b installed on my machine. I would like to uninstall R2014b without harming R2015b. They are both on C:\ drive, but R2014b is not in the start->All Programs->MATLAB area. What is the prudent way to uninstall just R2014b? Thanks.

Are you hurting for disk space? Normally, I would opt to leave both of them installed so that if there is ever a compatibility issue with code you have both versions to work with.

Hello!

I am working under windows 10 and I would have liked to delete Matlab2014a. I have been trying many times the control panel--> uninstall option and running the uninstall.exe in the main Matlab folder, but neither of them worked.

After many hours...I tried the following steps, and it was worked:

1) Right click to the uninstall exe (in the matlab folder, where you nstalled the matlab)

2) Compatibility problems solving

3) Trying suggested configurations

4) You should check all of checkboxes

5) Test the program

6)Finally, the uninstaller was working.

I hope that it is going to work and help to everyone.

Best regards,

Szabi

What worked? It doesn't make sense.

1. Right click on WHAT exactly? What file? There is no uninstall.exe file in my "C:\Program Files\MATLAB\R2021b" or in my "C:\Program Files\MATLAB\R2021b\uninstall" folder.
2. What exactly does Step 2 mean? Where would I see something that says "Compatibility problems solving" and what do I do when I see it?
3. What exactly does Step 3 mean? What suggested configurations? I don't see anything that says that.
4. What checkboxes?
5. Test what program?
6. How did you get the uninstaller working if there is no installer to be found in start->All Programs->MATLAB or in the Apps Control Panel?

I just uninstalled an older matlab version using the uninstall.exe in C:\Program Files\MATLAB\YOURVERSION\uninstall\bin\win64. This worked just fine for me. It leaves you with some folders and files left that you can remove manually.

Be cautious after Matlab has been uninstalled. The uninstall assistant will ask, if you want to deactivate your licence. You should cancel if you intend to continue using matlab on your machine.

Go to Control Panel and select Programs and Features. Then locate MATLAB r2014B and click the uninstall button.

I tried that. I went to Control Panel->Programs->Programs and features. but I am not seeing the R2014b; I only see the R2015b. I see R2014b folder on my C:\ drive.

Then you can just delete the folder from Windows Explorer/ File Manager. Edit your Environment variable to remove any folders in your path that have R2014b in them.

Did that work for you? If it's no longer in the control panel then Windows doesn't know how to uninstall it so you basically have to do it yourself. This means deleting the files and getting rid of other remnants like folders in the PATH environment variable. There will also stuff left over in special folders under c:\users, so go there and search for any folders that mentions R2014b and delete them. Let me know if that works.

I didn't do anything. I just leave it there as before, for now. Will report back when I have time to look into it. Thanks for all the help.
