What are bcmwlcoi64.dll Error Messages?


Dynamic Link Library bcmwlcoi64.dll Errors

bcmwlcoi64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like bcmwlcoi64.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. 3DP Net) could share the same bcmwlcoi64.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when bcmwlcoi64.dll is attempted to be loaded either when 3DP Net is starting up, or in some cases already running. Some of the most common bcmwlcoi64.dll errors include:

Your bcmwlcoi64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with 3DP Net), or deleted by a malware infection. Furthermore, bcmwlcoi64.dll file corruption could be caused from a power outage when loading 3DP Net, system crash while loading bcmwlcoi64.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix bcmwlcoi64.dll 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 bcmwlcoi64.dll 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):

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

If the Step 1 fails to resolve the bcmwlcoi64.dll error, please proceed to the Step 2 below.

Step 2: If recently installed 3DP Net (or related software), uninstall then try reinstalling 3DP Net software.

You can uninstall 3DP Net software by following these instructions (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button

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 bcmwlcoi64.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

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

If Windows Update failed to resolve the bcmwlcoi64.dll 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 bcmwlcoi64.dll 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 bcmwlcoi64.dll file version. We maintain a comprehensive database of 100% malware-free bcmwlcoi64.dll files for every applicable version of 3DP Net. Please follow the steps below to download and properly replace you file:

    Windows 10: C:\3DP\Net\Broadcom\Wireless\v7n\
    Windows 10: C:\3DP\Net\Broadcom\Wireless\v7\
  4. 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 bcmwlcoi64.dll problems.

Download bcmwlcoi64.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying bcmwlcoi64.dll to your appropriate Windows system directory. 3DP typically does not release 3DP Net DLL 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 bcmwlcoi64.dll and all other DLL files for 3DP Net. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
