I had an issue when I launched the programme after the upgrade: during the "database upgrade" phase, it errors saying that some xxx-genre.xml file was locked and then emm crashes.

I fixed this by setting the programme to run as administrator. All is good now.

This ought to be specific to my setup:
Windows 2012 R2 and EMM is installed in C:\PortableProgramFiles\

I took the liberty to edit the first post... I think most of all users are unable to scroll down to read important information ;-)

I carefully read all messages :-)

Yes, that hint is missing in the Alpha thread. Looks like I've wrote that only in the old Ember 1.4.7 thread.

FYI: Ember is still a portable application. Portable means that Ember saves all settings and temporarly files inside the installation directory. Windows has some security rules for "C:\Program Files" and normaly it's not allowed to change, delete or create files in this directory while normal run-time. For this reason we don't use this path as default installation path in our install wizard.

So you've to start the application as Administrator to get the right to edit, create or delete files, otherwise Ember will crash.
