While attempting to install Access Manager, the installer tells me I require Web Server 7.0, which it highlights. It then tells me I require DSEE 6.2, which it highlights. This last cycle repeats for ever, blocking any progress.
Which platform are you running this installer on ? Does it do the same if you select SUN One Application Server ?
I installed JES5u1 on Sol.Sparc several times. No issues of this kind. I had both WebServer, ApplicationServers both Interactive and Silent installs.
