Downgrading 10.4.10

Is this safe?

I've just purchased Pro Tool 7.3 MPowered and it won't launch as my powerbook has OS 10.4.10 installed and Pro Tools requires 10.4.9

I've read that if i run an Archive & Install from the install disk then run the 10.4.9 Combo Updater from apple.com i can downgrade but how safe is this and will it reformat/erase my mac??

Thanks,

YDR.

You might check and see if you can receive a free upgrade to 7.4. I just bought Pro Tools LE 7.3 and got a free upgrade. It now works with Leopard. I don't know if Mpowered is the same or not. Go to the website or call Digi if you need more assistance.

It says this:
"

thanks... but do i not need to be able to launch pro tools before being able to register?

How do i register the product if it won't launch?

Thanks in advance.

Try to contact their support staff. The link provided by Thedspeth has a Support -> Contact page.

Here is where you register your product... You don't do it within the program. Once you register, you should receive an email that will give you instructions on how to download 7.4 and install.

Okay so i claimed my free 7.4 upgrade but according to the Digidesign website it's compatible with Leopard but not OS 10.4.10 so it looks like i still need to dwngrade to OS 10.4.9...

So, how do i go about doing this and is it safe? The OSX install discs i have are 10.4.3 and i've downloaded the MacOSX Combo10.4.9 (PPC) updater from apple.com. Is this all i need and will it install 10.4.9 without wiping my hard drive and apps?

Thanks, YDR

If you have a bootable 10.4.3 disk. Then do an archive and install of it. Whihc will save yoiur environment. After which you install the 10.4.9 combo update.
