I have an HP DV7-1175nr with Vista Home Premium and an MSDN subscription. My Vista disk labeled July 2008 Vista with SP1 will not upgrade this to Ultimate.
1. Running the upgrade while entering the key and selecting the option to update the install process returns an error “An error has occurred Windows installation will have to restart”
2. Running the upgrade bypassing the authentication simply disables the upgrade option.
There is plenty of disk space (200GB) and I am selecting the correct 64 bit version of Ultimate.
Please help. I need to upgrade so I can use Virtual PC 2007 for a Sharepoint Development Server.
This thread was a very similar situation, but was unsuccessful as well.
I don’t see why it should be a problem unless the original OS were 32-bit, but your model # pulls up w/ specs including 64-bit Vista. Perhaps the MSDN disc requires a clean install, although you’d think the option wouldn’t be available if that were the case.
However, Virtual PC 2007 will work with Home Premium, even if it’s not listed as a “supported” OS on their site & may give a warning (I had Vista Home Premium x64 w/ SP1 running VPC2007 fine). Make sure you have VPC 2007 SP1:
