Looking at the way the versions are posted, I have to say I am a little bit nervous on the way you and us can work with the same fully qualified version.
Explanation: On November 29th I downloaded the DW7_2018-11-07.zip file. I got a 8475 setup version and a 8375 build version
Today I used the same link to download the file, I got a DW7_2018-12-07.zip (the month is different) and the setup version is 8514, but after installation the build displayed is still 8375
In fact I never got the 8450 build you described.
So where is the "official" and qualified version ?
Thanks in advance for your feedback.
PS : the build version number I get is from the Administration tool, etiher the welcome screen or A propos
