Wscuiex.cpl is not a valid win32 application error

I was running the Mozilla Firefox when I received this error message “Error Loading C:WINDOWSsystem32wscuiex.cpl, 1% is not a valid win32 application.” 

 
I have been utilizing Mozilla Firefox since before and everything was working normally. It just starting yesterday that this error has been continuously happening until today.  I am just wondering if you have a win-win solution on my problem because I cannot rely on myself. My knowledge on computer is very limited.
 
I tried referring this to my Auntie who is a computer instructress but she was not able to resolve the issue. According to her, the error message is caused by the viruses that are residing on my laptop.
 
Is my aunt’s perception correct? How can I fix it? Thank you very much in advance for your help.

You normally receive that error when running an unsupported program on your computer. But if it is with Mozilla Firefox, the problem is probably with the files. Try to uninstall and reinstall the web browser. Download the free version of Revo Uninstaller and install it. Once installed, start Revo Uninstaller then select your Mozilla Firefox among the applications and click “Uninstall”.

Follow the normal uninstall process. When uninstall is complete, click “Scan” to scan your computer for any leftover files and delete everything it finds. This removes everything the program created on your computer. When it is finished, close Revo Uninstaller then install Mozilla Firefox back. This should fix the problem. Try also installing the latest. Go to the Mozilla Firefox home page to get the latest.
