What are bitcount.h Error Messages?

General bitcount.h Runtime Errors

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

bitcount.h could not be found.
bitcount.h error.
bitcount.h failed to load.
Error loading bitcount.h.
Failed to register bitcount.h / Cannot register bitcount.h.
Runtime Error - bitcount.h.
The file bitcount.h is missing or corrupt.

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\Perl64\lib\CORE\bitcount.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 bitcount.h file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with ActivePerl), or deleted by a malware infection. Furthermore, bitcount.h file corruption could be caused from a power outage when loading ActivePerl, system crash while loading or saving bitcount.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.

How to Fix bitcount.h Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your bitcount.h issue. These troubleshooting steps are listed in the recommended order of execution.

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
When you see the search box, type "System Restore" and press "ENTER".
In the search results, find and click System Restore.
Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the bitcount.h error, please proceed to the Step 2 below.

Step 2: If recently installed ActivePerl (or related software), uninstall then try reinstalling ActivePerl software.

You can uninstall ActivePerl software by following these instructions (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
In the search box, type "Uninstall" and press "ENTER".
In the search results, find and click "Add or Remove Programs"
Find the entry for ActivePerl 5.28.1 and click "Uninstall"
Follow the prompts for uninstallation.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many bitcount.h error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".
In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
If updates are available for download, click "Install Updates".
After the update is completed, restart your PC.

If Windows Update failed to resolve the bitcount.h error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

If Those Steps Fail: Download and Replace Your bitcount.h File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate bitcount.h file version. We maintain a comprehensive database of 100% malware-free bitcount.h files for every applicable version of ActivePerl. Please follow the steps below to download and properly replace you file:

Locate your Windows operating system version in the list of below "Download bitcount.h Files".
Click the appropriate "Download Now" button and download your Windows file version.
Copy this file to the appropriate ActivePerl folder location:

Windows 10: C:\Perl64\lib\CORE\
Windows 10: C:\Program Files\MATLAB\R2019b\sys\perl\win32\lib\CORE\
Windows 10: C:\xampp\perl\lib\CORE\
Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve bitcount.h problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.

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

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