Legacy (unsupported) Versions
As of OSX 10.7 I am no longer supporting running iCal Dupe Deleter on OSX 10.5. However you can download the latest PPC version which runs on OSX 10.5 Leopard for both PPC and Intel.
Although I believe iCal Dupe Deleter v1.2 is far superior, you can also download the original version which also runs on OSX 10.4 Tiger.
