Yesterday, microsoft showed me once again, what it means to "obey".

I tried to install Microsoft SQL Server 2012 on a virtual machine with OS Windows7.
The installation-center asked me to choose an installation-folder for SQL-Server.
No matter what, for any folder i had chosen for the installation, the setup replied with the errormessage "The installation-folder is invalid"

So i considered asking our platform-services team, whether they gave me administrative rights for the vm.
They did. I had full access to the components of my vm.

After a few days i finally recognized, that i had picked a wrong iso for the installation of sql server.

Instead of sql server 2012 + Service Pack 3, i picked sql server 2012 ServicePack 3.

So after all, Microsoft tried to tell me by showing the message "The installation-folder is invalid", that the setup weren't able to find an installation of Microsoft SQL Server 2012.

God damned!!1!
