Are the wu's both 32 and 64 bit. I'm running an XP 32 bit system and it will run for 10-15 hours just fine and then everything errs out for a few hours

Like this

<core_client_version>7.6.9</core_client_version>

It seems always errs out at 1708 of run step, I'm wondering if its because its downloading 64 bit wu's
