Error while uninstalling or re-installing

Hi, after downloading and installing 2019b version I tried to uninstall the 2019a version but I get the following error message:

So i tried to re-install the older version in order to "repair" the installation and then uninstall but I get the SAME error. What can I do?

Hi Hao Lau, I solved by deleting the matlab folder D MATLAB R2019b. Then, in order to perform a complete uninstall, go to control panel and uninstall matlab 2019b (to delete the remaining files).

Thanks. But I can not understand how to unintall matlab 2019b after deleting the whole matlab folder.

Deleting the installation folder is the same of uninstalling (but normally is preferable to do it from control panel)

If the MATLAB uninstaller was unable to complete, try executing the uninstall.exe from $MATLAB\uninstall (where $MATLAB is the folder where MATLAB is installed). For example:

C:\Program Files\MATLAB\R2014a\uninstall\bin\win64

If you are unable to complete the uninstaller, you can try the following workarounds:

1) Re-install MATLAB and overwrite the current MATLAB folder. This will re-create uninstall.exe and should allow you to uninstall once complete

2) Manually delete the MATLAB installation folder.

Aside from removing the installation of MATLAB, you can remove the MATLAB entries from the Windows System Path. For help modifying the Path in Windows, see the related article:
