What are Flash.ocx Error Messages?

ActiveX-Related Flash.ocx Errors

Flash.ocx is considered a type of COM file, or Component Object Model, most commonly known as an ActiveX control. ActiveX controls like Flash.ocx are used by Trillian and other software to display media-related content. Therefore, your will most likely encounter a Flash.ocx error when attempting to load an audio or video clip, or view some variety of embedded website content. Some of the most common Flash.ocx ActiveX errors include:

Flash.ocx could not be found.
Flash.ocx could not be loaded.
Flash.ocx failed to load. The specified module could not be found.
Flash.ocx failed to register. The specified module could not be found.
Cannot find Flash.ocx.
Component 'Flash.ocx' or one of its dependencies not correctly registered: a file is missing or invalid.
Missing or broken reference to the file Flash.ocx.
One or more ActiveX controls could not be displayed because either: 1) Your current security settings prohibit running ActiveX controls on this page, or 2) You have blocked a publisher of one of the controls. As a result, the page may not display correctly.
Runtime Error 339: Flash.ocx not correctly registered.
The file Flash.ocx is missing or corrupt.
The Module 'Flash.ocx' Failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files. The specified module could not be found.
This program requires Flash.ocx, which is no longer included.

These OCX errors are most commonly due a missing or corrupt OCX. If your file is missing or corrupt, this could be caused by improper computer shutdown, or a malware infection, both of which could corrupt (or even delete) Flash.ocx. If your Flash.ocx is corrupted or missing, and therefore cannot be properly loaded by Trillian, this will result in an error message.

Finally, another common cause of Flash.ocx ActiveX errors can be contributed to an ActiveX-related subkey missing from the Windows registry. Broken DLL (Dynamic Link Library) references in the Windows registry can prevent Flash.ocx from registering properly, resulting in an ActiveX error. These broken references (registry keys) are usually triggered by a moved or missing file, or as a result of a leftover DLL file reference after a shared program has been uninstalled.

How to Fix Flash.ocx Errors in 4 Steps (Time to complete: ~5-15 minutes)

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

Step 1: Use Microsoft Register Server (regsvr) to Manually Register Your Flash.ocx File

When you install Trillian, or another software that uses the Flash.ocx dependency, the software should register the file automatically. Sometimes your OCX file won't get registered properly and will trigger a "Flash.ocx not registered" error. Thankfully, Microsoft included a handy built-in utility called "Microsoft Register Server" (regsvr32.exe) to enable you to manually re-register your Flash.ocx file.

How to re-register Flash.ocx from an elevated command prompt (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
In the search box, type "command" (do not presss ENTER yet)
While holding CTRL-Shift, hit ENTER.
You will be prompted with a permission dialog box.
Click Yes.
Type this command: regsvr32 /u Flash.ocx
Hit ENTER. This process will UN-register your file, allowing you to RE-register it.
Type this command: regsvr32 /i Flash.ocx
Hit ENTER. This process will RE-register your file.
Close the command prompt window.
Re-start Trillian.

regsvr32 /u Flash.ocx

Step 2: 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 Flash.ocx error, please proceed to the Step 2 below.

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

You can uninstall Trillian 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 Trillian 6.1.0.17 and click "Uninstall"
Follow the prompts for uninstallation.

After the software has been fully uninstalled, restart your PC and reinstall Trillian software.

If this Step 2 fails as well, please proceed to the Step 3 below.

Trillian 6.1.0.17

Step 4: 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 Flash.ocx 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 Flash.ocx 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 Flash.ocx 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 Flash.ocx file version. We maintain a comprehensive database of 100% malware-free Flash.ocx files for every applicable version of Trillian. Please follow the steps below to download and properly replace you file:

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

Windows XP: C:\Windows\System32\Macromed\Flash\
Windows 8: C:\Windows\System32\Macromed\Flash\
Windows 8.1: C:\Windows\System32\Macromed\Flash\
Windows 10: C:\Windows\WinSxS\wow64_adobe-flash-for-windows_31bf3856ad364e35_10.0.16299.726_none_4397f44608a754cf\

Windows 10: C:\Windows\System32\Macromed\Flash\
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 Flash.ocx 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 Flash.ocx Files (Malware-Tested 100% Clean)

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