Actually, it doesn't say that.  It says a specified module could not be
found, without specifying which.  Windows could be more helpful in its
error messages (which version of Windows is this?).

It could well be.  Any DLLs that fileGT.dll depends on must be in the same
directory or in your PATH.  Those DLLs are modules specified by
fileGT.dll, hence the confusing error message.
