Following error is shown. The user rights for logging folder have been checked and seem to be ok.
What could be the issue, and what logging should we check?
There is most likely an issue with downloading or installing the CefSharp webbrowser engine. The Cube logging (first tab) should provide more details on what goes wrong (e.g. unable to download the file from the DMA, no permissions to extract, ...).
It was indeed a problem with cefsharp.
The Cube logging showed it failed to install Chromium due to a signature not being available.
Manually installing resolved the issue.
We experienced the same after upgrading to 10.3.4
There was a fix in DataMiner Cube feature release 10.3.6:

Happened to me recently, and you can get the CefSharp here in case you have that issue
