Cannot install ADE 3.0

[coffee_80]

I'm able to download the Installer from the adobe website for ADE 3.0. However, when I try to install it, a message pops up saying that the certificate has expired and asks if I'd like to continue anyway. So I do. After it's finished installing, a successful installed message shows up. But I'm unable to find ADE 3.0 anywhere on my hard drive. Only the Installer is on my computer, not the program.

How can I get ADE 3.0?

I'm having problems getting borrowed library ebooks onto my e-reader, and it's been suggested that I use ADE 3.0 and not ADE 4.5.

Thanks

Which OS do you used exactly?

[coffee_80]

Mac OS X 10.11.6

Under Finder > Programs you found no Digital Editon?

[coffee_80]

No, there's no Digital edition 3.0. I have 4.5 installed, could that affect installation of 3.0?

[Nanaky]

Then first uninstall the current version bevor your install the 3.0 Version.

But why do we get an expired certificate? That certainly does not feel right, esp. coming for such a large company.

I didn't continue.  Thanks, Pierre
