DesktopAppConverter woes, Windows 10 v.17134

Question

I'm trying to convert my Win32 app from its MSI into UWP appx package using Desktop App Converter, so that I can update it in the Windows Store. Here's the steps.

When I downloaded the Windows_BaseImage_DAC_17134.wim file and tried to install it, I got this at the end (I'm not sure if it means anything):

Here's the same as a text:

VERBOSE: Removing any pre-existing NAT network
Get-NetNat : Invalid class
At C:\Program Files\WindowsApps\Microsoft.DesktopAppConverter_2.1.1.0_x64__8wekyb3d8bbwe\converter_util\ContainerNetwor
kSetup.ps1:158 char:24
+         $existingNat = Get-NetNat
+                        ~~~~~~~~~~
    + CategoryInfo          : MetadataError: (MSFT_NetNat:root/StandardCimv2/MSFT_NetNat) [Get-NetNat], CimException
    + FullyQualifiedErrorId : HRESULT 0x80041010,Get-NetNat

Then during the conversion process (that worked many times before) I got this:

C:\DesktopAppConverter\2ca66a48-91ab-4885-93cf-c9d6c325f3b2\shared

Does anyone have any idea what all this means?

PS. All these error messages have nothing to do with my app.

Answer 1

I ran into the same issue and solved it by turning off "Real-time protection" in the "Virus & thread protection settings".
