Same here for 1.10.2 and 1.10.3
(Had a previous working version installed before but had to delete after a previous hardware issue).
The error message 'The db name must have at least 4 characters' starts with a first character for the name field remains and the Finish button is greyed out. Many characters don't work, the only change is when unaccepted characters are entered. Trying other options on DB type or Content do not have an effect. Uninstalled, tried a different version etc.
Restoring DB seems to be Importing, but does not result in anything on the left side of the panel either.
