@Jessie your question has been answered in this thread in which not only how to install is covered, but also included are clear warnings about package conflicts that can result from using another Distros Repository and that the File Manager is an integral part of Desktop management.
You seem intent on trying out many different versions in spite of the evidence that the problems you cite appear on older or newer versions.
This is indicative that the issue is not the versions, but some other configuration, extension or file that is interfering with the proper execution of Nemo (e.g. Python).
