Hi MATLAB Central,
I am trying to install MATLAB with several toolboxes for some computational biology, such as Simbiology, Statistics, Curve Fitting, and Bioinformatics. Trouble is, when the installer is at 97% completion and is performing post-installation tasks, the following error message occurs:
The application encountered an unexpected error and needs to close. More information can be found at log file here
The file mentioned gives the following abbreviated messages:

Dear team,
I started the installation of Matlab yesterday. Everything was going ok , however it has not finished the post-installation tasks since yesterday but Matlab seems to keep doing tasks as it does not force the log out...
Could you please be so kind to help?
Thank you very much.

Maria.
