Method ‘Upgrade’ not found when executing Configuaration Wizard

Today I decided to install all updates on my dev VM (Win Server 2013 with SharePoint 2013). After a successfull install of all updates. I wanted to execute the configuration wizard to finish the updates. But it now tell me the following error message:

“Oh wonderfull, every day a new error…” I thought. But after a bit of googleing around, I found a Hotfix (http://www.microsoft.com/en-us/download/details.aspx?id=42898). After installing it, I¬†executed the wizard again, and boom it works for now.
