thats for an upgrade, though same error message. Mine is a fresh install

I finally found a work around it, after 2 days of PURE HEADACHE

I called M$ support and was asked to pay £199 ex vat to get a technician call me back.

The problem was the fact that i was running a 64 bit version, finally found a work around here
