So I just installed LW 5 on a PPC-based Mac running Tiger. I get a message saying "Could not launch the application [LW] because it requires a version of Java that is not installed."

So I'm screwed. There's no way to run LW 5 on this Mac. How do I get back to the old LW? Why is there no warning to the 2 million or so PPC users that they're about to nuke their LW capability?

Geez.

You can revert back to 4.18.8... there's info about downloading the older version for both basic & Pro users here: LimeWire 5 is only compatible with intel computers running Leopard OSX 10.5 or later

Looks like LW have now updated their download pages (Pro page shows the same) to provide info about which Macs can run LW 5

If you go in via limewire.com, there's no warning whatsoever. When you click on the non-pro DL link, you see this:



...and the LW5 DL starts automatically. You install it, and you've nuked LW.

Nope. The LW 4.18 installer refuses to install over LW5, at least for me.

Why doesn't the LW5 installer check for the required system before nuking me? This is a basic installer function. The Limewire guys need to wake up.

Now I'm hosed- what next?

You will need to remove the file called instal limewire.pkg from the Receipts folder in order to install LW 4.18; Receipts folder sample image. Also trash the LW 5 Program folder. Then install LW 4.18
