No, you can only have one version installed. Note there are workarounds to do this, but nothing official. There are some tools to help test by using the various engines.
Plus later versions of IE allow you (in dev tools) to specify IE version.
Ich versuche, IE6 unter Windows XP zu installieren, dies wird jedoch in der Benachrichtigung angezeigt
Msgstr "Die Installation ist nicht möglich, da eine aktualisierte Version von IE auf dem Computer gefunden wird".
Kann ich IE6 installieren, ohne die aktualisierte Version zu deinstallieren?
