Data Loader error Invalid API version specified on the URL

Knowledge Article Number 000193110
Description I downloaded DataLoader from my preview sandbox, but now I cannot connect that Dataloader to my production org.   I receive the message, "Invalid API version specified on the URL."
Resolution You cannot use a higher version Data Loader to connect to an org with a lower API version but you can use a lower version Data Loader with a higher version API.
  • For example, you cannot use DataLoader v. 30 (SP'14) to connect to a Winter '14 org, because W '14 version uses API v.29.
To resolve, you can download Data Loader from your production org so that the API versions match. The lower API version of tool will work with higher API version but not vice versa.
