Well, the file extension is '.err' so I can't open that file either.
that's why i asked you.
And i didn't changed any default things in install
and first post was about V17.2 i've tried several times to install ansys by changing another versions but the error has occurred each time.
that file was found in an answer given by a respondent on this site.
now i'm trying to setup the 'Ansys student 18.2' again.
in this time installed in correct path but the error is as a before.
