Installing theme problem

Hello, i'm a new user here!!!
I bought the full 3.4 theme collection and im trying to install it.

When i stared to copy all plugins at the same time, the nopcommerce crashed. After it, i tried to install plugin by plugin. But i got this:

Each plugin a had this:
The partial view 'AdditionalPanelsToUpdate' was not found or no view engine supports the searched locations. The following locations were searched:
~/Themes/Tiffany/Views/NopAjaxCart/AdditionalPanelsToUpdate.cshtml
~/Themes/Tiffany/Views/Shared/AdditionalPanelsToUpdate.cshtml
~/Views/NopAjaxCart/AdditionalPanelsToUpdate.cshtml
~/Views/Shared/AdditionalPanelsToUpdate.cshtml
~/Administration/Views/NopAjaxCart/AdditionalPanelsToUpdate.cshtml
~/Administration/Views/Shared/AdditionalPanelsToUpdate.cshtml
~/Plugins/SevenSpikes.Nop.Plugins.AjaxCart/Themes/Tiffany/Views/NopAjaxCart/AdditionalPanelsToUpdate.cshtml
~/Plugins/SevenSpikes.Nop.Plugins.AjaxCart/Views/NopAjaxCart/AdditionalPanelsToUpdate.cshtml

What a need to do?

Thanks,

Hi,

Could you check if the view AdditionalPanelsToUpdate.cshtml is in ~/Plugins/SevenSpikes.Nop.Plugins.AjaxCart/Views/NopAjaxCart/ ?
