What are ACTOC10.CHM Error Messages?


General ACTOC10.CHM Runtime Errors

ACTOC10.CHM file errors often occur during the startup phase of Office, but can also occur while the program is running. These types CHM errors are also known as “runtime errors” because they occur while Office is running. Here are some of the most common ACTOC10.CHM runtime errors:

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\Program Files\Microsoft Office\Office10\1033\ACTOC10.CHM

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


Most CHM errors are due to missing or corrupt files. Your ACTOC10.CHM file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Office), or deleted by a malware infection. Furthermore, ACTOC10.CHM file corruption could be caused from a power outage when loading Office, system crash while loading or saving ACTOC10.CHM, 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 ACTOC10.CHM Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying ACTOC10.CHM to your appropriate Windows system directory. Microsoft typically does not release Office CHM 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 ACTOC10.CHM and all other CHM files for Office. An incorrectly installed CHM file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
