DVArchive requires Java is set to 1.4.2, even if you ran the upgrade. To tell the operating system to go back to java 1.4.2, follow the following steps.

Open Applications/Terminal

Enter: cd /System/Library/Frameworks/JavaVM.framework/Versions
Enter: ls -l CurrentJDK

The terminal should reply with the following, showing your current Java version is set to 1.5.0:
lrwxr-xr-x 1 root wheel 5 May 11 16:36 CurrentJDK -> 1.5.0

Enter: sudo rm CurrentJDK
Enter: sudo ln -s 1.4.2 CurrentJDK

The terminal should reply with the following showing your current java is set back to version 1.4.2:
lrwxr-xr-x 1 root wheel 5 May 12 09:47 CurrentJDK -> 1.4.2

Done!

Reversing the process sets you back to CurrentJDK 1.5.0, should you require it.
