One can access Application Lifecycle Management using the Internet Explorer browser. However when ALM is accessed using non-supported version of IE, One can see the message from ALM that a non-suppported version is been used. Hence one need to be aware about the supported version of IE before going for installation.
Internet Explorer 7 is not supported by ALM 12.00.
ALM 12.00 supports IE versions 8, 9 and 10.
Please do note that, when opening ALM from an unsupported browser, the following message appears: "You are using an unsupported browser. ALM supports Internet Explorer 7, 8, 9 and 10". However ALM 12 does not support IE 7.
