[BUG]
Resolved 💬 2 comments Opened Apr 3, 2026 by billso-sudo Closed May 12, 2026
Preflight Checklist
- [x] I have searched existing issues and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code
What's Wrong?
OS: Windows 10 Pro
Claude version: 1.569.0.0 (from log path)
All services confirmed running: vmms, vmcompute, hns
Features confirmed enabled: Microsoft-Hyper-V-All, VirtualMachinePlatform, HypervisorPlatform
bcdedit hypervisorlaunchtype: Auto
WSL2: not installed
Error from log: HRESULT 0x80370102 - Cannot create system since Hyper-V is not installed on the host
What Should Happen?
Claude Cowork should run without telling me "Virtualization is not available
Claude's workspace requires Virtual Machine Platform, but the virtualization service isn't responding. Restart your computer to resolve this."
Spent over an hour with Claude Chat and Powershell trying every recommended fix. It finally directed me here.
