Change Language of Runtime

Hi,

I want to make a solution with multiple language option. (I am currently using Central Europe version of FileMaker, supports Turkish interface)

Let me summary the stuation.

I have 3 Runtime Folders. (with same binding keys)

a- For adding and editting records

b- For Turkish distribution

c- For English distribution

User use folder a for data entry. Then run the "prepare files" script to place lastest file into folder b and c. (only .usr file, other files are already placed)

I want to runtime exe in folder b runs as Turkish, runtime exe in folder c runs English.

Runtimes are open in Turkish as default. I have open Runtime in folder c and change language to English and Restart the runtime.

But after I changed language, the file does not open and gives an error: "The primary file test is either not part of this application, is damaged or already open"

If I delete runtime registry keys, It starts without problem but in Turkish.

How can I define languages for my runtime file?

Thanks
