Can't get 1.1, 1.2, oe 1.3 to install on iBook

[Mungojeff]

I have a G4 ibook running mac system 10.4.8.
I have Dig Perf 4.6.1 upgraded successfully from the web.
I am running MSI 1.0 and would like to upgrade to the latest version.
However, when I try to use the installlers for .1, .2, or .3, they installler just spins saying "searching hard disk" and nothing more ever happens.
I have my iLok installed while I am doing this, and have repaired permissions before.

I suspect it may be an auth problem?

MOTU responded to an email to ask Apple........

Thanks for any help.
