I tried answering this question according to what I have learned and it was incorrect, however this is an excerpt from MSDN:
"A DTS package can be saved on the 64-bit server, and a DTS package can be run against a SQL Server 2000 (64-bit) dataset, but the package must run from a 32-bit machine that is set up with SQL Server 2000 tools."
Doesn't that mean that you CAN run it?
