Problem opening a NT20 screen project

[Winall 0]

Hi all,

My customer sent me a HMI project file for NT20-ST121B to convert the screen data to a newer series. Problem is the project file was created by DOS software and  NT-Series Support Software cannot open it directly.

So when I used Import function to import the project file (with .m2s extension) to NT-Series Support Software, the following error appeared:

The error message didn't give me any hint as to how to import it. I guess it has something to do with Direct Access version of the program.

So I tried NTS233 for DOS to open it. But it reported an error like this:

 

Can anyone give me a hint?

Thanks a lot.
