249249| On a Windows device, Cowork tasks fail, the app shows **Failed to start Claude's workspace** with a message under it about a Windows update, or Claude can't read some attached files in Chat, such as Word, Excel, or PowerPoint files | The device has installed the Windows update released September 8, 2026, but not Microsoft's later update that fixes the problem. The September 8 update stops Claude's workspace from reaching files on the device. Cowork tasks and Advanced file analysis in Chat need the workspace. | Install the latest Windows update on the device and restart it. On Windows 11 24H2 and 25H2, the fix is KB5129195. No Claude Desktop update is needed. See [Resolved: Cowork on Windows](/docs/cowork/changelog#resolved-cowork-on-windows) in the Claude Desktop changelog. |
250250| Web search is on for your organization, but a user does not have it, and under **Customize**, then **Connectors**, **Web Search** shows as not connected and **Connect** fails, while chat works | A firewall or secure web gateway on that user's network path filters traffic by application. Claude Desktop connects to web search on your Claude for Government host over HTTPS, and such equipment can classify that connection as Model Context Protocol (MCP) traffic and block it even when the host itself is allowed. | Ask your network team to allow this traffic to your Claude for Government host for the affected users. The user's `main.log` records each failed attempt, including any block page the network returned. Then have the user select **Connect** next to **Web Search**, or restart the app. |
251251| The app shows **Failed to start Claude's workspace** with a download error under it, or Chat conversations and Cowork tasks fail to start with "Host Claude Code binary not available. Check that the download completed." | Claude Desktop could not download a complete, verified copy of the Cowork workspace or the [agent helper](/docs/third-party/claude-desktop/installation#endpoint-security-software) from `downloads.claude.ai`. This usually means a proxy or web filter on the device's network path is blocking or altering the download. | Follow [Cowork workspace or Claude CLI fails to download](/docs/third-party/claude-desktop/installation#cowork-workspace-or-claude-cli-fails-to-download) in the Claude Desktop documentation. |
252| On a Windows device, the app shows **A Windows security policy is blocking Claude's workspace**, and Cowork tasks don't start | A Group Policy or MDM policy applied to the device assigns the **Log on as a service** right without the `NT VIRTUAL MACHINE\Virtual Machines` group, or lists that group under **Deny log on as a service** | Follow [Windows security policy blocks the Cowork workspace](/docs/third-party/claude-desktop/installation#windows-security-policy-blocks-the-cowork-workspace) in the Claude Desktop documentation. |

253254For anything else, the app writes its log to `~/Library/Logs/Claude-3p/main.log` on macOS, `%LOCALAPPDATA%\Claude-3p\logs\main.log` on Windows, and `~/.config/Claude-3p/logs/main.log` on Linux. The log records which configuration keys were read or dropped and why. The diagnostic report from the verification checklist produces a bundle, without conversation content, that you can send to your Anthropic representative.
