Export model to create table

[Don Pick]

Running MySql version 5.7 on Windows 7 pro

In WorkBench version 6.3 I am trying to execute the sql code to create a table.
I created a model for tblA
Then I clicked on File > Export > Forward Engineer SQL CREATE script
A screen showing options appears. I selected “Generate DROP statements Before each Create”
I click Next
The sql object export filter appears. I clicked on the SHOW FILTER button and it shows the correct table to be created.

I click Next
Now I see the sql code which will create the table.
I click on Finish and nothing gets created.

So, I redo the steps above except I click on “Save to Other file” and save the script to file named A.sql
But it will not save the script!! I keep getting the message “Invalid argument” but nothing will show me where the invalid argument is.

I have tried to save to several different folders . I made sure every folder has full write privileges because writing a Windows file can fail if privileges are inadequate.

Every time I get the error “Invalid argument” nothing shows me where the bad code is located. This is very frustrating.

Question 1: How do I save the code so I can execute it?

Question 2: is this a bug?
