Can't Install Amiga Forever

Clicking on Install Amiga Forever in the AF2006 Premium Edition launcher menu results in nothing more than the installation of Acrobat 5.0. Is there a work-around for this?

They say it is because Installshield needs to finish installing adobe acrobat 5.0. But I have installed, removed, and re-installed it, and the AF installer keeps wanting to install adobe acrobat 5.0 again. The Amiga Forever CD does not have acrobat or installshield on it, as far as I can determine. I am utterly baffled about what is going on.
I installed a Windows game that uses Installshield, and there was no such problem with that.

I've tried contacting AmigaForever's technical support, but got no reply so if anyone has any ideas I'd most grateful. My problem's slightly different. Previously I've been able to install AF with no problems, but after uninstalling so I could move it to a new HD now when I try to install it the installer attempts to write it back to the CD where there is no space to install and it won't let me change the installation destination.
