+# Windows troubleshooting
+
+This page collects confirmed Windows-specific symptoms that are still tracked in the issue
+tracker. It is intentionally brief: each entry records the affected version reported by users,
+a current workaround when one is known, and the canonical issue. Check the linked issue before
+assuming the same cause applies to a newer release.
+
+## Non-ASCII paths in CBM_CACHE_DIR or CBM_ALLOWED_ROOT
+
+**Symptom:** configuration appears not to persist, the config database cannot be opened, or
+repositories that should be inside `CBM_ALLOWED_ROOT` are rejected.
+
+**Reported on:** v0.9.0.
+
+**Workaround:** avoid non-ASCII characters in these two environment-variable paths. Repository
+paths passed directly as CLI arguments were not affected in the original report.
+
+**Tracking:** #1165.
+
+## Upgrade completes but the Windows binary version does not change
+
+**Symptom:** an upgrade appears to download successfully, but
+`codebase-memory-mcp --version` still reports the old version.
+
+**Reported on:** v0.8.1.
+
+**Workaround:** use the current `install.ps1` flow to reinstall/update the binary, then verify
+the version explicitly. The current README also treats the install script as the supported update
+path on Windows.
+
+**Tracking:** #1168.
+
+## Index worker hangs, crashes, or leaves an empty worker log
+
+**Symptom:** `index_repository` repeatedly reports worker hangs/crashes, or the referenced
+`.worker-*.log` is empty.
+
+**Reported on:** v0.9.0.
+
+**Workaround:** for repositories containing large binary/media/model directories, exclude those
+paths with `.cbmignore` before retrying; that workaround was confirmed in #1132. If the project
+is small or mostly source, keep the failing tree intact for diagnosis and follow the canonical
+worker issues instead of assuming the same trigger.
+
+**Tracking:** #1130, #1132, #1145.
+
+## Antigravity 2.0 configuration is not picked up
+
+**Symptom:** installation completes but Antigravity 2.0 does not see the MCP server/hooks, while
+legacy Gemini configuration is present; duplicate large binaries may also be left on disk.
+
+**Reported on:** v0.9.0.
+
+**Workaround:** verify the configuration files that Antigravity is actually loading before
+re-running installation, and avoid keeping duplicate binary copies once you have confirmed which
+one is active.
+
+**Tracking:** #1161.
+
+## OpenCode is installed but not detected
+
+**Symptom:** `codebase-memory-mcp install` detects other clients but skips OpenCode.
+
+**Reported on:** v0.9.0 on Windows.
+
+**Workaround:** use the README's manual MCP configuration path for OpenCode while automatic
+detection is being tracked.
+
+**Tracking:** #1167.

+letting this page become a second issue tracker.
