Hi guys,

When ever I download something in google chrome and I click show containing folder, an error comes up saying "class not registered".
The same thing happens in uTorrent when I click show containing folder on one of my torrents. After that the program becomes unresponsive I was hoping you guys could give me a solution to fix this problem.

Thanks in advance, QW

I also found out that when I click personalize or change resolution on the desktop, it gives an "interface not suported" error. Note that the "class not registered" error has only been happening since a couple of days.

You could try system restore to a point before the problem started.

If its a virus malwarebytes didnt pick it up and I dont see how it could be connected to uTorrent in another way. Why do you think it has something to do with uTorrent?

Thanks for all the responses so far guys, even if it didnt help I still appreciate you guys taking the time to think about it, and I hope you can help me find a solution.

Thanks in advance, QW

I disabled system restore for security reasons, because I read a guide that stated its more secure to leave it off.

Utorrents and P2P are both widely known in many cases to be a method of choice for the bad guys to infect computers all over the world. Some torrents are good things but many are used to get stuff free that arn't free and the bad guys use this soft spot to slip in many virus, Trojans, key-loggers, and many more. On this site and many other very good sites that help people clean their computer of such things and do some reading. It will give you a better understanding. This is my thoughts on torrents. Some have a different opinion.

Hmm, okay, but do you have an idea what is causing the error? It is also happening on google chrome and I also cant personalize or change the resolution on my desktop anymore. When I try to personalize or change resolution I get a different error: "No such interface supported".
As for my stand on torrenting, its 100% legal in The Netherlands and I completely agree with my country's policy.

I have no problem with you and your country making those choices. The question I was trying to approach is the security of using a torrent not whether it is legal or not.

Same Problem in Latest Chrome in Win 7 x64

I'm having the exact same problem with Google Chrome, Comodo Browser, RockMelt (all chrome based browsers) and I do not use torrents etc. There must be a common denominator and I have seem this problem being discussed all over the web since 2009, so its nothing new - just yet to find a fix.. Luckily I have more than 1 notebook all running Win 7 x64 and 1 Vista Home Premium S0 x86 and it's only happening on my Dec 2009 ACER Extensa 5635Z.

If anyone has a solution yet, please let the 1000's of the same problems being posted on the web, be resolved once & for all. Google are you Home?

Thanks in advance guys.
