22.10.5 - Silent install -> "Entering ExecNetFx"

[david.jonsson]

Hi,
My Silent install have worked fine on 21.10.9
I’m now upgrading all Robot machines with Studio (for troubleshoting) + ServiceMode.

I’m on Windows 10 and .NET Framework 4.6.1
This is my set of pre-reqs:

choco install dotnet-6.0-desktopruntime -y
choco install googlechrome -y
choco install microsoft-edge -y

This is my MSIExec string:
MSIEXEC /i "C:\temp\UiPathStudio_22.10.5.msi" /l*v "c:\temp\3. InstallStudio_msi.log" /q ADDLOCAL="Studio,DesktopFeature,Robot,RegisterService" APPLICATIONFOLDER="C:\Program Files\UiPath" PACK AGES_FOLDER="c:\nuget"

The install carries on, but after some 32.000 lines the log starts to generate compile errors.
The partial log attached InstallStudio_22.10.5.log.zip (977.5 KB)
Is this expected?

The MSIExec have been running for some +30min.
Is this expected?

What is this compilation ExecNetFX about?
I can’t find any files generated from it.
Check lastwritetime:

Get-ChildItem -path "C:\ProgramData\UiPath" -Recurse -File | sort lastwritetime | select -last 10 |format-table -property @{Expression={(New-TimeSpan -start $_.LastWriteTime -End (Get-Date)).Days};Label="Days"},Length, FullName

It’s related to ngen.exe:
https://www.google.com/search?q=ngen+windows

When running the install manually, ngen is not called from MsiExec.

Just surprised it’s only activated when running the MSI in silent mode.

I guess we’ll have to accept its added for a reason.
