I've Got A SITE in wordpress the hyperlink is www.studium.cl. After I open in IE, the browser opens a window having a message just like a "you have to install adobe expensive player blablabla.."

After i install adobe expensive player increase the website, this seems again.

How do i fix this, or what's the reason for this?

1) Perhaps you have closed all of your IE home windows? (or simply reboot your pc to make certain all did close)

2) Have you got admin rights on your pc, to ensure that Expensive could really install?
