Hello, I am new using OpenModelica since yesterday.
I would like to see '*.FMU 'file which done by other person with OMEdit so I keep trying to open it by using this path "FMI - import FMU"
However, whenever I try this I got the error saying that,

Error has occurred while loading the file/library C file's path/filename.mo...Unable to load the file/library
Redefining class(es) file name which already exist(s). Delete the existing class(es) before loading the file/library C:/file path/filename.mo

It is keep occurred even if I delete the .mo file and try again. and I have the library which name is same as the .mo file

Am I doing rightly? or is there other way to open it? because  I want to see what is in side the file I got from other person.

best regards,
Areum
