shassouneh,
I had the same problem and just solved it. With my problem Search did not work either "Start -> Search" also yielded a blank window. Additionally, I was having trouble installing Flash - it would just do nothing. In addition, USATODAY.com for instance would not show the changing window in the upper left-hand corner.
A few days ago I removed FSecure Anti-virus suite and installed McAfee 8.0i. Prior to installing McAfee, I created an install point, so I know it worked prior to the install. However, I had trouble removing F-Secure and due to the fact that I had previously had McAfee (an older version) I had to resort to heavy registry edits to remove all traces of both programs - as uninstall had issues.
On to how my system was fixed. I first tried registering the three dll's -
regsvr32 jscript
regsvr32 vb script
regsvr32 /i mshtml
I received an error on the vb script one - failed to register.
I then was going to install Restore by right clicking the file in the system32\resotre directory but the install option was not available (presumably because it was still installed). I ran the file srdiag.exe and left the widow it opens for about a minute - it created 6 to six log/txt files.
I then entered the string you provided to manually run Restore from IE, and it ran. I then created a restore point and browsed the calendar.
I left the IE window with Restore in it open and ran Restore from Control Panel / Performance and Maintenance / System Restore and it worked! Thinking that this was just because it was already running I closed restore (but not the window that I.E. creates and it ran again. I then closed all IE windows and it ran.
Rebooted and it works properly. Search now is now longer blank and when I launched IE the pages that previously had some issues work properly. Upon launching IE flash instantly started, it was ready to install - probably cued from my previous attempts.
Though it was not my original post - thanks to all who have posted.
Hope this helps you.
