I had a similar error but it was from a base CMS 6 site (not an upgraded 5 site).
My solution was simply to delete the base site (which I had been playing about with), re-install a blank version 6 site and then install the demo site on top of that.
I realise this isn't exactly your issue and you have the extra stage of the upgrade from version 5 to 6 but I thought I would share my solution.
Cheers,
Robert

Hi,
I have a default Episerver CMS 5 SP2 site which I upgraded to Episerver CMS 6.
I tried to install demo pages on this page which resulted in the error below.
Anybody have some advice for how to fix this?
Kind regards,
Jon Haakon
