Hi @patalou, thanks for your detailed report. After asking around, I am afraid that the error logs you shown is not a typical issue. A cursory search online showed that this error, “The Burn engine cannot run with an MBA under the .NET 4 CLR on Windows 7 RTM with .NET 4.5.2 (or greater) installed.” Seems to be related to Windows upgrades from previous version where .NET was not properly updated or installed.
The common advice amongst the threads I found has been to uninstall and reinstall .NET runtime libraries or alternatively try installing the software in compatibility mode which it seems you already tried unsuccessfully. Did you try already reinstalling .NET?
