[WenJunJi01]

OS: Windows 11 (ARM64)
Build: .NET SDK 7.0.100-preview.7.22362.31 from https://aka.ms/dotnet/7.0.1xx-preview7/daily/dotnet-sdk-win-x64.exe

Repro steps:

1. Prepare a clean windows arm64 OS　
2. Install x64 .NET 7 P7 SDK

Expected Result:
The SDK should install successfully and CLI works well.

Actual Result:

1. Install it stuck and unable to complete the installation.
   

2. Check the x64 dotnet path and Programs and Features
   

3. After adding the x64 dotnet path to the environment variable, checking the dotnet info at the CLI also gets stuck.

x64 .NET 7 P6 SDK can be successfully installed on the arm64 OS. But we checked the x64 dotnet path and found that some packages were lost, and dotnet command could not be recognized.

This issue cannot repro with x64 6.0.400-preview installed.

Let's retest this once we have codeflow from this PR and a coherent runtime: #14124 I wonder if this is an issue of just the builds aren't ready yet.

[marcpopMSFT]

@WenJunJi01 , we should have a signed preview 7 build tonight. Can you retest with that? Thanks.

[WenJunJi01]

@marcpopMSFT , verify with the signed preview 7 build- 7.0.100-preview.7.22370.3(runtime-7.0.0-preview.7.22369.4), and this issue still reproduces.

@WenJunJi01 does this impact the runtime installers as well or only the SDK?

[WenJunJi01]

@marcpopMSFT This only affects SDK installers. The x64 .NET 7 runtime can be installed successfully.

[WenJunJi01]

@marcpopMSFT Today we tested the latest .NET 7 RC1 SDK from main branch of https://github.com/dotnet/installer. It can be installed successfully on arm64.

Dotnet info:

However, it didn't work well. The following error occurs when creating a new project in CLI. This may be due to this bug dotnet/runtime#71856, even the error info is different. And I have updated the bug comment.

Unfortunately, this problem reproduced today when we installed the x64 .NET 7 SDK-7.0.100-rc.1.22403.8.

From the error above it appears that dotnet new is hitting some of the workload install code for MSIs. This appears to an issue retrieving the ISystemInformation class. I'm waiting for an arm64 machine to investigate this further

Hi @joeloff, today we validated on SDK 7.0.100-rc.1.22408.3(runtime-7.0.0-rc.1.22403.8). The x64 SDK can be installed, but we are still unable to create the project and encounter the following error.

[joeloff]

I believe there's an issue with COM under emulation and trying to confirm.

[WenJunJi01]

There is another new bug tracking this issue: dotnet/sdk#27032

[WenJunJi01]

This issue cannot be reproduced with latest main build (x64 SDK 7.0.100-rc.1.22414.5) from https://github.com/dotnet/installer. The SDK installs successfully and works fine when creating, building, and running projects.

[WenJunJi01]

Close it as it is fixed.
