claude-code - 💡(How to fix) Fix Claude is repeatedly flagging yukonSilver not supported (status=unsupported) and never booting the VM [1 comments, 2 participants]

Error Messages/Logs

TL;DR

The issue is likely due to a bug in Claude Desktop's internal platform detection, causing it to incorrectly mark the system as incompatible, and the user should report it to Anthropic for investigation.

Guidance

• The error message "yukonSilver not supported (status=unsupported)" suggests a compatibility issue detected by Claude Desktop, despite the user's hardware and OS being capable.
• To verify the issue, check the system's Hyper-V settings and ensure that the vmms service is running, as the user has already done.
• Since the issue is reported as a bug in Claude Desktop itself, the user should report it to Anthropic with detailed system information, including the Claude Code version (1.2773.0) and operating system (Windows 11 Pro, x64).
• The user may want to try checking for any updates to Claude Desktop, although the issue is reported to occur with the latest version.

Notes

The issue seems to be specific to the user's system configuration, and without more information, it's difficult to provide a definitive fix. The user should await further investigation from Anthropic.

Recommendation

Apply workaround: Report the issue to Anthropic for investigation, as the problem is likely a bug in Claude Desktop that requires their attention.
