Problem: The compiler was unable to compile the specified file into the .chm file. This problem may occur if the compiler cannot locate a file referenced in the [OPTIONS] section of the project file or a window definition (e.g., the HHC.
Result: The .chm file is corrupt and should not be used.
Solution: The most likely cause for this is insufficient disk space. First make certain that there is sufficient disk space on the drive where your .chm file is being created (usually the same drive as your project file). If you cannot free the space on that drive, you can change your project file so that the .chm file is created on a different drive. If freeing up disk space doesn't resolve the problem, try rebooting your system, particularly if you've recently been editing the file. It may still be held by another process that never completed. If the problem occurs because a file is missing, you will need to identify the file and move it to the intended location. As a best practice to avoid this problem, be sure to explicitly add all project files to the project, rather than relying on the compiler to pull in the files by reference.
