* First screen appears. See attached "Zurich install location select". It is grey and cannot be altered.
* Next screen appears/ See attached "Zurich install activation failed". There is now only one way left, end the install procedure.
It's entirely normal ( as the installer clearly says ) you are not able to change the installation path, you are not supposed to, if you installed other FSDT products.
But something is missing in your report, after you select Next, you are supposed to see the License Activation screen, which asks for the activation key. If you don't enter one, or some error happens *there*, THEN the installer will return with the red cross message in your 2nd screenshot.
Have you seen the License screen ?
