[QGIS-Developer] Log file? - QGIS not starting

[magerlin]

Having problems installing QGIS on a colleagues brand new Win 10 PC.
I have recently installed without problems on my own identical PC.

We have tried 3.4 and 3.10 both as Standalone and from OSGeo4W.

But situation is the same: 

QGIS 3.4:
<http://osgeo-org.1560.x6.nabble.com/file/t202356/3%2C4.png> 
C:\Program Files\QGIS 3.4\apps\qgis-ltr\bin\Qgis_app.dll          
does exist on PC but the .env file does not



QGIS 3.10:
<http://osgeo-org.1560.x6.nabble.com/file/t202356/3.png> 

Here the .env file exists and contains this:
