Post Installation Step Error in Sitecore.Reference.Storefront.Powered.by.Microsoft.Dynamics.8.2.507.update

[hetaldave]

After I installed the mentioned update package, I got the error below -

It seems like the assembly needs to be updated from "Sitecore.Reference.Storefront.InstallPostStep, Sitecore.Reference.Storefront.Powered.by.Microsoft.Dynamics.dll" to "Sitecore.Reference.Storefront.InstallPostStep, Sitecore.Reference.Storefront.Common.dll" - as I can see the type in question Sitecore.Reference.Storefront.InstallPostStep in the Sitecore.Reference.Storefront.Common.dll.
