What are comdef.h Error Messages?


General comdef.h Runtime Errors

comdef.h file errors often occur during the startup phase of Orwell Dev-C++, but can also occur while the program is running. These types H errors are also known as “runtime errors” because they occur while Orwell Dev-C++ is running. Here are some of the most common comdef.h runtime errors:

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\Program Files (x86)\Dev-Cpp\MinGW64\x86_64-w64-mingw32\include\comdef.h

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.


Most H errors are due to missing or corrupt files. Your comdef.h file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Orwell Dev-C++), or deleted by a malware infection. Furthermore, comdef.h file corruption could be caused from a power outage when loading Orwell Dev-C++, system crash while loading or saving comdef.h, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Download comdef.h Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying comdef.h to your appropriate Windows system directory. orwelldevcpp typically does not release Orwell Dev-C++ H files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing comdef.h and all other H files for Orwell Dev-C++. An incorrectly installed H file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
