Add-ons that need another add-on first
Some add-ons build on another one. Install the one they need first, or XenForo will refuse. Which D.C Style add-ons have dependencies.

Some add-ons build on another add-on and cannot run without it. XenForo knows this: every add-on lists what it needs, and XenForo refuses to install it until those needs are met. The fix is almost always the same. Install the add-on it needs first, then install the one you wanted.
How XenForo checks requirements
Each add-on declares its requirements in its addon.json file: the XenForo version, sometimes a PHP version, and any other add-on it depends on, with a minimum version for each. When you click Install or Upgrade, XenForo checks every one of them before changing anything.
If something is missing, the install stops with a message such as:
- "The following requirements for More Threads were not met:" followed by the missing add-on or version.
- "Cannot proceed with installation/upgrade of More Threads because it may not meet the minimum requirements."
Nothing has been changed at that point, so it is safe to install the missing piece and try again.
D.C Style add-ons that need another add-on
| Add-on | Needs | Notes |
|---|---|---|
| More Threads | Thumbnail 1.0.0 or newer | Thumbnail is free. More Threads builds its related-thread list on top of it. |
| Advanced Download Pro | Advanced Download 1.0.0 or newer | Advanced Download is free. Pro adds download timers and bypass groups on top of it. |
| Rock Paper Scissors | DragonByte Credits 5.6.0 or newer | DragonByte Credits is a separate add-on by DragonByte Technologies, not by us. Members bet its credits in games. |
Optional extras
Some add-ons work on their own but do more when another add-on is present. XenForo does not require these, so nothing stops the install:
- Widgets: the image layouts of the New Threads and Random Threads widgets show thread thumbnails from Thumbnail. Without it, use the list layout.
- Forum Statistics: the resource tabs appear when XenForo Resource Manager is installed, and the media tabs when XenForo Media Gallery is.
Install and upgrade in the right order
- Install the add-on that is needed, and make sure it shows as enabled under Installed add-ons.
- Check its version meets the minimum in the table above. If not, upgrade it first.
- Install the add-on you wanted. How to install a XenForo add-on.
The same order applies to upgrades. If a new release says it needs a newer version of another add-on, upgrade that one first.
Tip: Keep the needed add-on installed and enabled for as long as you use the one that depends on it. To remove both, remove the dependent add-on first. Disable or uninstall an add-on.
XenForo and PHP versions count too
The same check covers your XenForo version, and sometimes your PHP version. If the message names XenForo or PHP rather than another add-on, see Find your XenForo, PHP and MySQL versions and Reading version numbers. For other install messages, Common add-on installation errors covers the rest.
