How to fix the ActiveX Error 32009 rtfNonUniqueKey

ActiveX can pose a security risk especially if you installed a program that is not signed or validated. Google Chrome has strict settings for disallowing plugins that seem to be a security threat.

If you happen to receive a message telling you that the plugin was stopped because your browser security settings disallow it, you should check if its a virus infection before you attempting to reinstall it. If your investigation shows that you are experiencing an access problem, then you can try lowering your security settings and installing the plugin again.

You might also be having a problem with Windows Defender. If that is the case, open your security center and lower the security settings.

Toolbar plugins differ between company providers. Once installed on a browser, these can display compatibility issues with ActiveX controls. To address any possibilities of plugin related issue, try the following steps:

• Try disabling plugins that you suspect are causing the conflict.
• You can try disabling them one at a time to see if you still get the error.
• Reinstall ActiveX Control and check again if you still get the error when you use your plugins one by one.
• If you are experiencing a problem that is related to a certain program, you can try uninstalling and then reinstalling that program, then check if the problem persists.

You have tried reinstalling your plugin but it's still telling you that the plugin is not installed. No matter how many times you retry installation, it comes up with the same message. To resolve this, you should:

• Download and install SubInACL.msi from Microsoft download center. http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=23510
• Download and install the plugin you have been trying to install

We've discussed that the registry may be the reason your ActiveX is giving you an error. To resolve this, you may use the following tools:

• Registry checker tool - this tool scans your system registry for invalid entries, you when you run into a problem with settings in the registry, you can:
• Download Scanreg.exe via Microsoft.com
• Once downloaded, start the Windows Registry Checker tool by clicking Start, then Run.
• On the open box type scanregw.exe, and then click OK.
• You may alternately open a Command prompt and run scanreg.exe /restore then choose the registry backup on the list to restore your registry
• System File Checker - this tool works pretty much like a registry checker but this helps you find and repair corrupted or missing system files so it takes a bit longer to run
• To run the command, open elevated Command prompt by typing it on the search window, then right clicking Command Prompt and choosing run as administrator
• Type sfc /scannow on the prompt and wait until verification process is successfully completed
• Repair reinstall using your OS CD or flash drive
• The best way to repair your system software is still reinstalling it. Repair reinstall process helps you keep your files as you repair the operating system. Though, you need to make sure you back up your file if you indeed need to clean reinstall your computer. You will need to insert your installation media and restart your computer.
• Access your BIOS, the process differs from one computer model to another, it may be F1, F2, or Del button.
• Once there, go to boot section, set boot to the installation disk and save settings.
• For earlier version of Windows, you may need to tap your keyboard while you wait for the computer to access the installation disk.
• Choose the repair utility first instead of clean installing the OS. This may save you a lot of hassles. However, if the issue continues after rebooting your computer, then just back up files and do the clean reinstall.

Sometimes, you are not able to run ActiveX just because you have a problem related to your IP. To resolve your DNS conflict, do the following steps:

• Open your Network and Sharing Center. You may right click the internet icon on your system tray and click Open Network and Internet Settings. You may also go to Control Panel, then click Network and Internet, then click Network and Sharing Center.
• Click Change adapter settings on the left side, then right click on the network on which you are connected, either Ethernet or Wireless, and click Properties.
• Depending on whether you are using IPv4 or IPv6, highlight your Internet Protocol Version then click Properties.
• On the window that will open, you will see items that allow you to input Preferred DNS Server and Alternate DNS server. Click the radio button to select that.
• Change your DNS server to 4.2.2.2 (preferred) and 4.2.2.3 (secondary).
• These are DNS resolvers so once you apply those changes and try connecting to the internet again, you should be able to connect with no problem and utilize your ActiveX controls normally.

If you received an error that tells you your ActiveX failed to register, it will present you with a notification that tells you the name of a driver that needs to be re-registered. Take note of the driver name and follow these steps to do that:

• Log into Safe Mode by rebooting your computer and tapping F8 to access the startup repair tools.
• Once you are logged into Safe Mode, open Command prompt.
• On the prompt, type "regsvr32 C:\Windows\System32\xxxx.dll", where xxxx is the name of the driver that is specified in the error message.
