# Change the working directory to the application's installation directory by using the cd command (e.g. for Firefox <code>cd "C:\Program Files\Mozilla Firefox"</code> or <code>cd "C:\Program Files (x86)\Mozilla Firefox"</code>). '''Important:''' running the update from within another directory will fail to update the existing installation properly with Firefox 3.6.x and below, SeaMonkey 2.0.x and below, and Thunderbird 3.1.x and below.
# Close all instances of the application that are running on the system including those being used by other users before going any further. '''Important:''' not doing so will cause the update to fail.
# For Firefox 34.x and above, SeaMonkey 2.31.x and above, or Thunderbird 34.x and above run the following from the command prompt. The additional <code><path to installation directory></code> is used by applications for update staging and when manually applying a mar the value for this command line parameter must be the path to the installation directory.<br><pre style="white-space: pre-wrap;
