    i cant delete from reg, and i get an active x error when i do method 2. I cannot install any programs, and a lot of my windows become unresponsive. I am running Win7 ultimate on a custom machine, just built it in Nov. 2010. Haven’t had any problems untill a month ago. I have regcleaner program, i have run it, i have run AVG full scan, and I have even done some “ad fix programs” never bought any of them though. What can I do?

    No kidding – I just did this after a month of pulling out my hair with a new HP desktop with Windows 7 and IE9 but FINALLY got it working. I tried every other option I could find on the internet…disabling add-ons, removing the IE9 update, etc. I got this from a computer guy in the USAF AND IT WORKED!!!

    He said it is a problem with the embedded PDF in IE. Remove any and all PDF programs from your computer using “Control Panel/Programs/Uninstall a Program. Then Google or Bing “Adobe Reader 9.4.7 MUI” (I got that from my wife’s laptop with W7/IE9 that doesn’t have the same problem) and download/install it for free.

    That’s what worked for me on 1/11/2012…good luck!

    FYI: Reg cleaner is just pretty much a scam. I bought it but it never ever did ANY thing good for me at all, but they did refund w/o any hassle tho!
