I had the micro-p error after changing to an Acer AcerPower F1 PC due to the other system failing.
Thanks to this particular forum I changed from installing Geovision 6.1 to installing 6.0.5, which seems to work just fine.
Thanks for the support given to others. I know its been more than a year since this stuff was posted but a search found the answer here.
Thanks to Rory and the other founders for setting up the CCTV Forum in the first place.
