My name is Oleg, I'm from SEO Samba / SEO Toaster team.
Unfortunately we have an issue with CMS installation on some of Windows based servers.
We are working on a new package and that Windows issue will be fixed.
For now you could deploy SEO Toaster on Linux based server.
You can get working Linux environment like virtual machine on your Windows.
Here are few useful links:
There you can download a tool called "Vagrant" to run needed environment, and on second link, you can configure a server(vagrantFile) to run it with "Vagrant".
Please contact us if you have some questions.
