Can you download Internet Explorer 7 while keeping IE8 intact?

I am trying to log into a security dvr over the web but the unit requires IE7. If i uninstall IE8 I get prompted about security updates that used IE8 to download and if i uninstall they may not function properly. So can I download IE7 and keep IE8 intact?|||With the official versions, you can't. You could try to find a portable version of Internet Explorer 7, but it will be made by a third-party, thus untrustable. I've attached a link below to one of those third-party developed solutions. I cannot tell you it is trustworthy as I didn't install it.
