When attempting to download or update Steam games on their PC, many customers get the “Missing/Unavailable Content Manifest” issue. A manifest is a collection of files that describes the hierarchy of files and folders on a computer. During an update or game download, the Steam Manifest is loaded before the files are downloaded. Keep in mind that game files are split into numerous sections.

The manifest specifies the sequence and kind of files required to download or update a game properly. Steam pulls the other game files and combines them into one file after downloading the manifest. If Steam is unable to access or locate the manifest, it will effectively hang, and Steam users will see an error message.

What’s the deal with Steam’s “Missing Content Manifest”?


This problem is caused by a conflict that Steam faces when looking for the manifest file, the manifest file being corrupt or unreadable, incorrect regional settings, Steam setup, or DNS difficulties. This manifest file is very significant since it provides all pertinent information, such as the file’s integrity and how it is utilized to load the game.
