You switch modules on and off in one place, and the change takes effect at once. This page explains where the switches are, when a change takes effect, and what happens to lists that use a module that you switch off.

Where
Choose Modules → Manage modules… in the menu bar. The page lists every installed module with an Enable box, grouped by category, with its version.
A module that is on gets a line of its own in the Modules menu, above Manage modules…. That line opens a window with the settings of the module only.
You chose the modules during the installation, when the setup asked which modules to install and which of them to switch on. A module that you installed but did not switch on is on disk, and you can switch it on here later.
When it takes effect
Tick or clear Enable and press Apply or OK. The module starts or stops at once; you do not need to restart the program.
What happens to your lists
Switching a module off does not change your lists. The cues stay in place, with their titles and settings.
What the module showed disappears. A song cue without the song module is a line that shows nothing. When you switch the module on again, the cue works again.
Switching modules therefore never damages a list. A show can still go wrong if you switch a module off and then run a list that needs it.
Before a service
Check this screen when a computer has been reinstalled or updated, and compare it with what your list needs. It takes two minutes, and it prevents a problem that you would otherwise find during the broadcast.
Do not update modules during a service, because the modules stop for a moment during the download. See Info.
When the modules do not start
Modules run in a separate process, upmod-runner.exe. If that process cannot start, a window with the title Modules could not start shows the cause. None of these causes stops the base program:
| The message begins with | Usual cause |
|---|---|
| Windows refused to start upmod-runner.exe | Antivirus software, or a file that was blocked after it was copied |
| upmod-runner.exe is missing | The installation is incomplete |
| upmod-runner.exe started but did not respond | Antivirus software is scanning the program |
| upmod-runner.exe did not start in time | Antivirus software is holding the file. The program continued without modules |
| The installation is incomplete | The program and the modules are from different versions |
If antivirus software is the cause, the message names the folder to add to its exclusions. In the other two cases, reinstall the program, so that everything comes from the same version.
Where the modules are on disk
The modules are in C:Program FilesUltimate PlayoutModules, together with a small file that records which modules are on. You do not need to edit anything there: this screen writes the file.
