Unable to convert DCP files to XML using dcpTool on a Windows system

Errors:

• "*** Error: Unable to open file ***"
• "*** Exception thrown in main routine - probably could not access a file"

What we've tried:

1. Checked if the DCP files and their paths are correct. The files do exist and are in the correct path.
2. Tried to run the script from different locations, including running the script from the directory where the DCP files are located.
3. Made sure the dcpTool and its DLL files are in the correct folder. Initially, they were in the Cygwin directory, but later moved to C:\Program Files\dcpTool.
4. Modified the shell script (originally written for ZSH) to a Windows batch file to ensure compatibility.
5. Checked the DCP file and output XML file paths in the script to ensure they are correct and tried using both relative and absolute paths.
6. Tested the command directly in the command line to rule out any issues with the script itself.
7. Checked the dcpTool command and arguments to ensure they are correct.
8. Checked if there were any permissions issues by running the batch file as an administrator.
9. Checked the batch script syntax and added error checking and logging to get more detailed output.

We haven't yet been able to solve the problem, hence reaching out for further help. Any advice would be greatly appreciated.

Thanks!
