There are two possibilities here, Either you don't have the permission to install in the computer or your downloaded software is corrupted.

Solution 1: If your are not the administrator of the computer, then you are not entitled to do anything in the computer, unless the administrator give you the same level of his account or you belong to the power users. To fix this, ask for permission to install the software or give you the right access to do it yourself.

Solution 2: Download the software once again and try installing it and see if there might be some corrupted files. You might also consider reinstalling the browser associated with Thunderbird more specifically Mozilla Firefox.
