Obviously all .NET apps fail to start/run in Windows VMs (both “Windows 7” and “Windows 10”) after copying the VM to a computer with Core-i3 1115G4. Copies are error-free (disk image checksum verified, repeated once), Windows boots well. But starting .NET apps just does not work. Currently, the app’s splash screen appears, after a second disappears without any message, process in task viewer detail view is gone. Inspection with Sysinternals Process Monitor showed nothing useful yet. I cannot start installer for the app again, going to be desperate a bit.

The app I’d like to use is Microchip Studio 7.0.2594, which uses Microsoft Visual Studio 2015 and .NET 4.5.x or 4.6.

On source host (Core-i7 7567U) and also on other hosts (CPUs 6th-gen desktop and 10th-gen mobile Core-i7) it runs well – there the installation procedure ran.

Comparing the CPU features of 7567U with 1115G4 shows that both have Intel® SSE4.1, Intel® SSE4.2, Intel® AVX2, but only the 1115G4 – where the apps deny to run – additionally has Intel® AVX-512.

The installation procedure was achieved unter VMware 12, the running and the problematic VMs both run under VirtualBox 6.1.22.
.NET fusion logfailures didn’t tell me anything useful yet.

Any ideas what to try? Except installing Windows from scratch? How could I remove .NET in case the .NET uninstallers don’t run from “programs and features” (delete files and registry entries)?
Side question: is the goal (running Microchip Studio 7.0.2594) reachable with some Linux and Wine or such, and how?
