Most probably is a MS security update issue.

Run the un-installer.
Re-start the computer.
Auto Fix IE7 security settings (back-up the OS registry before executing the command below):
Open a Command Prompt by clicking on "Start", followed by "Run", and type CMD in the box, then click OK. When the Command Prompt window opens up, type this line exactly as entered, being careful that you use spaces where needed. I will suggest that you copy the syntax below :
secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose

Download the stand-alone Adobe Falsh Player:
