What exactly do you mean by "is not working"? Can you please be more specific?

When we open default examples of CPLEX, the software run as it is expected. However, when we create new project the software  does not work. A "covering problem" example can run, but when we copy the mod and dat files into new created project the software says "No "Configuration1" run configuration." (this definition was translated in English because CPLEX selected language as Turkish. )

How exactly did you create the offending project? Did you use the "Create new OPL project" menu item? Can you please attach all files from the offending project? In particular the project and oplproject files (they may both be hidden).

We used the " Create new OPL project" and could not run attached files.

When I try to run your project here I get this error:

Internal error: multi-byte error, wrong encoding? C.

My guess would be that this is due to the non-English characters in your run configuration name. It is called "Yapılanış1". When I rename this to "cleanname" then everything works fine. Can you please try renaming your run configuration to something that only has English (7bit ASCII clean) characters?

Thank you for your help. The program itself creates the project files and name them in Turkish characters automatically. As you mentioned, the error is caused by this reason. The error message given comes out in Turkish again and it means different than what you mentioned. The program has some strange definitions and needs to be reconsidered in Turkish. Actually, while the installation process we selected language as English. When we started it Turkish was assigned as default language.

I have filed a bug for this issue: if the program creates the name in Turkish or allows renaming to Turkish then it should be able to deal with it and not raise errors with cryptic messages.

About the Turkish vs. English issues you may want to ask at the forum that is dedicated to OPL and monitored by the OPL/IDE experts. This forum is https://www.ibm.com/developerworks/community/forums/html/forum?id=11111111-0000-0000-0000-000000002053.
