TypeLib Problem

Thankyou in advance for any replies.

I have a problem, CCleaner cleaned everything up but one registry key will not clear, it keeps re-appearing in the 'problem' list after cleaning the registry and cannot be removed.

This is what is left in CCleaner:

Missing TypeLib Reference IVideoWindow - {B9AA1F11-F480-4054-A84E-B5D9277E40A8} HKCR\Interface\{56A868B4-0AD4-11CE-B03A-0020AF0BA770}

Do I need to either re-install something? If so, How and what?

Or, is there a way to clear this item (I've tried many times already).

In cleaning my laptop, have I removed something I shouldn't have?

I've never had a problem with CCleaner before and I have been using it since 2004.

Please be gentle with me, I am an older person and I am not as tech savvy as some of you (lol!).

Thankyou again x :)

I am using the latest CCleaner version v 3.27.1900 (64 bit)

reading my signature should answer your question, you should research what the entry is (usually i**** entries are your security software but not always) and (if safe) add it to your exclude list

Chances are you have a software installed that you currently use which is re-installing the key. You could either ignore it constantly re-appearing or set and exclusion the next time it shows up by right-clicking it and selecting to exclude it.

Thankyou for replying. I will try excluding it when I run ccleaner again. :)
