When attempting to import a solution in Dynamics 365, the import fails with the following message:
"The import of the solution [solution name] failed. The following components are missing in your system and are not included in the solution. Import the managed solutions that contain these components ([name of missing solution] ([solution version])) and then try importing the solution again."
You may also see a reference to error code 8004801d.
This error occurs if you are trying to import a solution that depends on other components that are not in your Dynamics 365 organization.
Example: You have a development environment where you created a solution (Solution A) that contains a custom entity (Widget). You created another solution (Solution B) that depends on a component in Solution A (ex. added a new field to the Widget entity). If you try to import Solution B into another organization (ex. your production organization) that does not already have Solution A installed, you would encounter this error.
Review the missing component details shown in the import dialog. If there are other solutions listed that are not already imported in the organization where you are trying to import this solution, import those solutions first before trying to import this solution.
Example: Continuing with the example from the Cause section above, you might see that the list of missing components shows one or more rows where the Managed Solution column references Solution A. This indicates you would need to import the mentioned version of Solution A before you will be able to successfully import Solution B.
If the error message refers to a Microsoft solution, refer to the following list of solutions and where they can be found if they are not installed in the target organization:
Dynamics 365 Sales LinkedIn Integration
NOTE: If you want to uninstall these solutions, they need to be uninstalled in the order of the above list.
