I am trying to install flashplayer,but halfway through the install it asks me to turn off internet explorer, by going to task manager,
processes, and uninstall anything to do with I/e.but there are 5 I/e. if I click end process it say's I might lose data or it might upset my system.
I have not got a clue what to do so I cant 'go any further.  can you please help.
I've never heard of that. All you have to do is close IE the normal way, not with Task Manager. MAKE sure you are downloading Flash Player from here: https://get2.adobe.com/flashplayer/    (and be sure to uncheck the McAfee download option first). Then save the installer, close IE, and run the installer.  I have just tried your link ,and got the same result, click install/ then unticked MacAfee,  click run.it gets to about 75% then asks me to
close I/e. you say close it the normal way ,what is that.The same way you close any applications: Either "File - EXIT" or click on the red "x" in the upper right HAND corner 
I don't understand your ANSWER, if I close I/e by red crossing it. I just use another browser  like Firefox or chrome, to ask the same question how do I install adobe flash player. I get the reply follow this link ,install run etc. etc.. then it tells me to close I/e. back to square one.You close IE and other browsers after the installer is running. The Installer does not use the browser.When you download the flash player installer you save it to your computer. Then you close the browser. Then you double-click on the file that was saved and run the installer.
