Simply run LDView.com instead of LDView64.exe, and you should then get error messages if it runs into problems. Note also that if you include the LDView install path in your system path, you can just run LDView, and it will use LDView.com automatically (even with 32-bit LDView, although you're using 64-bit LDView).
FYI, LDView.com supports -v to show errors and warnings (default is just errors), as well as -q to silence almost all errors, and -qq to silence all errors.
