Basic workarounds in case of errors while importing projects and other operations with projects

If an exception occurs while importing a project or another error occurs while working with the project and this error is not otherwise specified, perform the following workarounds:

1. Clean the project.

2. If the error still occurs, delete the project-internal database and have it created anew:

   1. Start the explorer of the operating system and go to the folder of the workspace.
      If you are unsure what the folder of the workspace is, select in Neuron Power Engineer: menu File, command Switch Workspace and Other... – The opened dialog displays the folder of the workspace.

   2. Move on into this sub-folder: .metadata\.plugins\com.logicals.projectindex\database\project-name\

   3. In this sub-folder, delete these files: project.mv.db and project.trace.db

   4. In the project explorer of Neuron Power Engineer: Delete the project. Make sure that Delete project contents on disk (cannot be done) is cleared in the dialog.

   5. In the project explorer again: Import the project. Now the project-internal database is created anew.
