The first indication that an issue has occurred will be failure of the step that backs up the database in the form of an error message stating: mysqldump.exe has stopped working.
It is possible to proceed beyond that point by ignoring the error. If it is chosen to ignore the error the next indication of an issue will be that after a potentially long period of "Contrast is starting up...", the console will start to display MySQL related errors such as the following:
WARN (MysqldResource.java:240) Unable to connect to the mysql database.
ERROR (DatabaseServer.java:135) [DEFAULT] Unable to start database
WARN (MysqldResource.java:283) mysqld pid-file not found: C:\Program Files\Contrast\data\db\MysqldResource.pid
INFO (MysqldResource.java:490) launching mysqld (contrast-database)
INFO (MysqldResource.java:259) mysqld running as process: 1234
But Task Manager show no indication that the process mysqld.exe is actually running.
The Windows Event Viewer will likely contain errors such as:

The 3.5.8 release of Contrast includes an upgrade of MySQl from version 5.6 to 5.7. The new version of MySQL has a dependency on the Visual C++ Redistributable Packages for Visual Studio 2013 which may not be installed on the system.
Ensure that the appropriate version of the Visual C++ Redistributable Packages for Visual Studio 2013 are installed on the system. For a 64-bit system, be sure to install the x64 version of the package even if the x86 version is already installed.
