Loads of errors after interrupting installation IE9

[daan5000]

Hello,

Last week I tried to install IE9 after some annoying pop-ups. The installation got interrupted somehow. I didn't care about that because I would never use that browser anyway.

Soon I realised I was not able to use Windows Live Messenger anylonger. After logging in, an error occurs: "Can't find ordinal 379 in DLL-files iertutil.dll" (translated from dutch, so it could be a little different in English). After this error, msn closes directly.
I did some research and I read I could fix this problem by editing some internetoptions in the control panel. But when I click on internetoptions, nothing happens.

MSN isn't the only application giving this error. I experienced the same error in some other applications like paint.NET.

Also, I can't open VMWare anylonger. It runs in processes but on screen nothing happens. Skype closes directly after crashing, WOW won't start anylonger,... These are just some of the problems I experienced in the last 6 days.

I scanned my computer on viruses with NOD32 without any results.

Thanks in advance.

Welcome to Windows Seven Forums.

I think the most pain-free option would be a system restore to a point before you installed IE9.

Thanks for the quick answer but are there any other solutions? Frankly, this isn't the first time I'm having trouble with Windows (7). Windows never worked without problems here. Knowing the cause of this problem would be helpful in the future.

The cause for this current issue is the IE9 interruption. Live Messenger and other programs use IE components to "call home". This probably wiped and/or corrupted more than a few files.

Try running http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html#post14392 to see if there are file corruptions. This may need to be run 3 times, rebooting twixt each one.

Frankly, this isn't the first time I'm having trouble with Windows (7). Windows never worked without problems here.

Is this PC one you bought with Win7 installed, did you install it. Upgrade install or clean, fresh install?

What anti-virus are you running?

Is this PC one you bought with Windows 7 installed?
No, I've built my own pc. I downloaded Windows 7 Professional from MSDN with an academic license. My hardware is also recent.

Upgrade or clean install?
Clean install, always.

What anti-virus?
NOD32, switching to Norton now.

I'll post the results of the file checker soon.
