I have been trying to install the latest version of Flash Player and it will only go to 50%. When that happens, it will tell me I need to close Internet Explorer; I have IE 9. So, I go to close out of Explorer and and keep retrying to download but it won't let me. I do ont know what else to do. I also, am wondering what the difference betrween flash player and shockwave is.
Download the offline installer from http://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html#mai n-pars_header and save it to disk, then close all browser windows and run the downloaded installer.
Regarding your second question, do you mean Shockwave Player or Shockwave Flash?
