Right click menu

Hi all, new here, looks a great site.
Ok down to my problem, when i right click on the mouse on a folder, a windows installer tries to download updates from adobe acrobat,and after trying to install it,it states it cannot find the correct directory.
I don’t really want to update acrobat as i have the latest pro8 version,but secondly it is getting very annoying when everytime i right click anything the windows installer starts.
Anyone have any ideas how i can stop this.

Thanx in advance.

Ian
