What do you mean by "walk me trough" ?
I just installed core (with no errors) and installing ribbons shows "Error: Parameter Incorrect".
RibbonPictures folder is without any changes and DefaulAppPool has write permission on it.
Got an error:
System.ArgumentException: Parameter is not valid. at System.Drawing.Bitmap..ctor(Stream stream) at Nop.Services.Media.PictureService.ValidatePicture(Byte pictureBinary, String mimeType) at Nop.Services.Media.PictureService.InsertPicture(Byte pictureBinary, String mimeType, String seoFilename, Boolean isNew, Boolean validateBinary) at SevenSpikes.Nop.Plugins.ProductRibbons.Plugin.ProductRibbonsPlugin.() at SevenSpikes.Nop.Framework.Plugin.BasePlugin7Spikes.Install() at Nop.Admin.Controllers.PluginController.Install(String systemName)
Still problems with IE9 and IE10 (both desktop and metro mode).
I see, that for Nop Ultimate Plugin Collection supported nopCommerce versions are nopCommerce 2.3 - 3.0. But when dowloading trial, there are no files for version 3.
On this Wednesday ?
