Now, why would you want to partion yopur HDD? This only cracks me up. Get ONE MORE HDD... Anyways, if you only have one HDD, this really shouldn't be a problem, but I've never installed Windows and Office on different partitions - but in theory this should't be a prob. Removing the installation files is mandatory, it only takes up space anyway. Are you sure you've got enough space for the SP? Have you tried to re-install MS Office on the same partition as Win? If that works, call Bill Gates... Then the partitioning must be the prob - even though I cannoit understand why... Any progress?
