Hi midlander,
welcome to the forum
.
First of all: You've installed the .net framework 4.5?!!!!
Here's a short descritption what should happen after starting the updater.
The part you've downloaded and installed is 'only' the downloader for the autoupdater. After checking the version the autoupdater should be downloaded to the folder 'misc' in your installation folder, extracted there and copied to the folder 'resource'. Is there any folder in your installation folder of the updater?
kind regards
