I am using Internet explorer 8 and I was having a problem on a site I could not log on so they had me delete all cookies and browsing history and restart that solved their problem but now I had the problem of adobe poping up all the time every time I opened ANY new tab it poped up with the message that adobe was interfering and do I want it to run. I am NOT going to keep clicking EVERY time I use my damned browser. so I deleted adobe and tried to reinstall it but now it will not reinstall. I says nothing when I reinstall then when I try to install again it says it is already installed but when I check with unistall it is NOT there.
You can see with the diagnotic page what my system is
It's the security settings of Internet Explorer that caused these pop-ups; just readjust the security settings, and these pop-ups will no longer occur.
To reinstall Flash Player, try a clean install: http://forums.adobe.com/thread/928315
You shouldn't have to turn off protected mode to get the Player to work. You might be running into permission issues. See this FAQ for more details:
