Greetings,
The update of EEK is still not working properly
The Flash Stick with EEK that wasn't updated for several days was connected
I've got the same stack of “Access Violations” as in the initial post and later confirmed by
ryerman here The version of EEK is (was) the latest 1.0.0
.12; The update size was ~ 72MB
After killing the process & trying to update again there was a message about some files having wrong versions
After confirming a necessity to update there was another
(new) crash:

The process was killed again & the next attempt brought this:

Therefore I did not have any other option, but trying to download the whole Package again (~92MB)
That went fine and since (almost all) new signatures were included I updated straight after the unzipping and got just ~242KB of differential Additional Signatures, which was expected and ended successfully.
My regards
