borland C++ source code to read doc file

[lajet]

I have a problem in reading doc file.
I've developed a program whcih can open and read the file.
If the file is doc file it calls directly to the winword.exe that saved under the directory. But if the version that install in the computer is not matched, the problem started.
For instance, I copied winword.exe (xp version). But now i installed office 2007 in my computer.
So, when i click my program to read the file, the error message shown and exit.
How to solve my problem?
Please share your idea/suggestions.
I'm using borland c++ and FLTK GUI toolkit.
Thanks in advance.

What is the error message?

Are you sure that Office 2007 uses the same exe name and is in the same location?

There was a file format change between Office 2003 and Office 2007. I suggest you see if you can open and read your file using Word 2007.

Let me know what you find.

Let me explain more detail with example.
I have c++ project under d:/mytest folder.
So, i copied all application files(ms word application files) including exe under mytest folder to open doc file.(It is xp version)
It runs smoothly.
When i upgrade my computer to office 2007and i tried to open the doc file under mytest folder from my program.
Then, error shows that you want to run this application in safe mode or cancel.
Then, when i click cancel, it quit.
Instead of saving application files under mytest folder, if the program can call the default exe file which installed in the computer, it is better i think.
Because i need to distribute that project to users.
So, when application runs and clicks to read doc file, the program call the default exe(winword..etc ) which installed in user's computer is the good idea.
But i have no idea how to start the code.
If anyone of you can give me some idea/suggestion it would be greatful for me.
Thanks much inadvance.
