cursor can't be moved when entering installation dir \ReactOS

When you install ReactOS you get prompted for the desired installation directory. By default it shows "\ReactOS" and below there is an input field.

Using the arrow-keys does not move the cursor. So you cannot move the cursor left of a character. This means, that you cannot use the [del]-key to delete characters.

Tested with 0.4.7 RC1

Edit: I split this issue into 2. One covers the translation error and one covers the improvement for the cursor support.
