The Solution explained here is only a workaround which may or may not work depending on your privileges on Host Machine.
Make sure that you have applied all latest patches. Double check by starting Digi ESP -> Package Manager (You should be having an Internet connection)
If all patches are applied then make sure that you have followed the instructions mentioned in Installed NET+OS 7.5.2 and all updates but getting build errors like >> multiple definition of ***Mesh***
