Problem: Error: "Integrator Distributed Adaptor package not installed".
Solution: There are three possible reasons for this error.
1. The Integrator Distributed Adaptor package is not installed in the customer's account.
2. The user does not have read/write access to some of the custom fields for the objects in the package. These fields can be viewed in the profile settings for logged-in user profile.
- Go to: Setup > Profiles > Edit profile > Custom Field-Level Security and add read/write access to all the custom fields for distributed package.
3. The package is installed only for the administrator.
