Ups... I run it from a wrong dir.
Running it from inside calibre dir it shows:

link hasn't been detected!
link hasn't been detected!
Using proxies: {'ftp': '127.0.0.1:8080', 'http': '127.0.0.1:8080'}
Upgrading database to version 5...
Upgrading database to version 6...
Upgrading database to version 7...

Then shows UI with books...
When closing, no more output is shown.

Found the issue ...
For 0.5.14 this was my Calibre start script:

@echo off
echo Starting Calibre ...
set CALIBRE_CONFIG_DIRECTORY=%~dp0UserData
"%~dp0calibre\calibre.exe" --with-library "%~dp0Library"

This works for 0.5.14, but calibre 0.6.* seems to need to be started from Calibre directory rather than a parent directory, such as:

@echo off
echo Starting Calibre ...
set CALIBRE_CONFIG_DIRECTORY=%~dp0UserData
cd "%~dp0calibre"
calibre.exe --with-library "%~dp0Library"



Thanks.
