I keep getting internet script error messages even after ive installed an updated version of adobe flash

You probably just need to update it. Go to the adobe website and get the latest version - it's free!
Adobe flash player is used by many websites, such as YouTube, so you wouldn't want to remove it.

runaway script can involve 2 pcs software. one is java. if you don't use java, you can delete it thru control panel. the 2nd item is adobe. adobe flash recently updated. you can download a program called p.s.i. from secunia.com. it will show you all of your out od date software. since you did not indicate your operating system, i'm guessing you using a current or recent version of windows. good luck.

This problem can be fixed by editing script code.
I would suggest to un-install the browser.

• Clear all registry entries by using registry cleaner like Reginout
  
• Restart PC
  
• Install the latest version of browser
  
• Update the flash player
  

Hope the problem is fixed.

If you can update your Flash Player through "control panel", do so. If not, uninstall current version of Flash Player and download latest version here:
http://get.adobe.com/flashplayer/otherversions/
Choose your operating system, then the latest version of the Flash Player. You may want to save to file, then exit all apps, then open file and download. You have to be out of everything that accesses Internet for download to be sucessful. You will also want the latest version of Java. If you have it, again, see if you can update through "control panel", if not, you can either uninstall it first then get it here:

are you installing from a download or from a CD? I am not sure why you are installing an older version which lacks updates and patches. Here is a link to the newest version. Once again you have to completely remove the old one including trace files.
