Using syms, Matlab stops working

Using syms, Matlab stops working. Only quitting the program helps. I have Symbolic Math Toolbox, so I have no idea why it doesn't work.

[Star Strider]

See: "syms", "sym", and "mupad" functions cause MATLAB to freeze (link).

This is a known issue.

[Kapa Kudaibergenov]

What if at the end of the installation it always fails? Did anyone meet such a problem?

[Steven Lord]

In that case, please contact Technical Support using the Contact Us link in the upper-right corner of this page. Work with them to determine why the installation fails (sending them the exact text of the error you received will help with this) and how to get the update to install correctly.
