Hi @mstorsjo

Running this command gives error:

python vsdownload.py --accept-license --print-deps-tree Microsoft.VisualStudio.Workload.VCTools

this works but i'm not sure if this will cause any issues

Related to #135 .

From the manifest, the dependency chain is

Microsoft.VisualStudio.Debugger.Remote.DiagnosticsHub.Client (machineArch: arm64)
  Microsoft.VisualStudio.Debugger.Remote.DiagnosticsHub.Client (machineArch: x64)
    Microsoft.VisualStudio.Debugger.Remote.DiagnosticsHub.Client (machineArch: x86)
      (no dependencies)

But machineArch is not handled currently, so the dependency chain is parsed as

Microsoft.VisualStudio.Debugger.Remote.DiagnosticsHub.Client (machineArch: arm64)
  Microsoft.VisualStudio.Debugger.Remote.DiagnosticsHub.Client (machineArch: arm64)
    ...
