Tool(s) enabling installation of a solution are described. These tool(s) may follow appropriate security precautions to contain possibly dangerous code in a data file's solution even when the solution is installed from a local source, such as when a user is offline. These tool(s) determine what level of security is appropriate for a data file's solution based on the original source of the solution. The tool(s) may also and/or instead enable a user to edit a data file without the user having to discover or deploy a solution application governing the data file.
