MSB6004 Missing "ProgramW6432" environment variable on 32-bit systems

[chrisdaiii]

On 32-bit systems use:
dotnet msbuild WebApplication1.csproj -t:publish /p:PublishProfile=IISProfile

Output error:
C:\Program Files\dotnet\sdk\6.0.300\Sdks\Microsoft.Net.Sdk.Publish\targets\PublishTargets\Microsoft.NET.Sdk.Publish.MSDeploy.targets(171,5): error MSB6004: The specified task executable location "%ProgramW6432%\IIS\Microsoft Web Deploy V3\msdeploy.exe" is invalid.

The system has installed 32-bit WebDeploy, and the publish can be successful only after I manually set the "ProgramW6432" environment variable. Is this a bug of dotnet or msbuild?

Looks like a bug in the MSDeploy task:

sdk/src/WebSdk/Publish/Tasks/Tasks/MsDeploy/MSDeploy.cs

Lines 264 to 274 in db704c8

	if (string.IsNullOrEmpty(m_exePath))
	{
	string programFilesX86 = System.Environment.ExpandEnvironmentVariables("%ProgramFiles(x86)%");
	string msdeployExePath = System.IO.Path.Combine("IIS", "Microsoft Web Deploy V3");
	m_exePath = IO.Path.Combine(programFilesX86, msdeployExePath);
	if (!IO.File.Exists(IO.Path.Combine(m_exePath, ToolName)))
	{
	string programFiles = System.Environment.ExpandEnvironmentVariables("%ProgramW6432%");
	m_exePath = IO.Path.Combine(programFiles, msdeployExePath);
	}
	}
