Hi Chandana_Ramesh,

Please rerun the command with a --debug flag and share the command and the whole output.

From the message that you shared, it looks like the Analyzer.exe binary is not accessible:

• Verify the binary exists and is accessible: C:\Users\chandana.r\.databricks\labs\lakebridge\state\venv\lib\site-packages\databricks\labs\bladespector\Analyzer\Windows\analyzer.exe. If it’s missing, reinstall Lakebridge via the Databricks CLI. If it’s present, ensure it’s not quarantined or blocked.
• Check Windows Defender quarantine and add an exclusion for the C:\Users\chandana.r\.databricks\labs\lakebridge\state\venv\Lib\site-packages\databricks\labs\bladespector\Analyzer\Windows directory, then restore the analyzer.exe if quarantined.

Hope this helps.

Hi @aleksandra_ch ,

Please find the below attached complete output of command databricks labs lakebridge analyze --debug, as requested by you.

Also, the file C:\Users\chandana.r\.databricks\labs\lakebridge\state\venv\lib\site-packages\databricks\labs\bladespector\Analyzer\Windows\analyzer.exe is missing, and I couldn't find it even after re installing lake bridge through databricks cli.

Hi @Chandana_Ramesh , 

Please check if the binary was not quarantined by Windows Defender or any other security solution on your PC. 

Hello @Chandana_Ramesh!

Did the suggestions shared above help resolve your issue? If so, please consider marking the response as the accepted solution.
If you found a different approach that worked, sharing it here would be helpful for others in the community.

As @Advika suggested can you confirm if you can locate analyzer.exe . Seems like it doesn't exist which means some background process might have removed it if it was installed initially . 

Hi @Chandana_Ramesh,

The FileNotFoundError you are seeing means the analyzer.exe binary is not present on disk at the expected path:

C:\Users\chandana.r\.databricks\labs\lakebridge\state\venv\lib\site-packages\databricks\labs\bladespector\Analyzer\Windows\analyzer.exe

Since reinstalling Lakebridge via the Databricks CLI did not restore the file, the most likely cause is that Windows Defender (or another antivirus/endpoint protection tool) is quarantining or deleting the binary immediately after installation. This is a documented scenario in the Lakebridge project (GitHub issue #1811).

STEPS TO RESOLVE

1. Check Windows Defender quarantine history:
- Open Windows Security > Virus and threat protection > Protection history
- Look for any entries that show analyzer.exe being quarantined or removed
- If found, restore the file from quarantine

2. Add an exclusion for the Lakebridge directory:
- Open Windows Security > Virus and threat protection > Manage settings
- Scroll to Exclusions > Add or remove exclusions
- Add a folder exclusion for:
C:\Users\chandana.r\.databricks\labs\lakebridge\

3. If your organization uses a centralized endpoint protection solution (CrowdStrike, Carbon Black, Symantec, etc.), you may need to request your IT/security team to whitelist that directory or the analyzer.exe binary specifically.

4. After adding the exclusion, reinstall Lakebridge:

databricks labs install lakebridge

5. Verify the binary is now present:

dir "C:\Users\chandana.r\.databricks\labs\lakebridge\state\venv\lib\site-packages\databricks\labs\bladespector\Analyzer\Windows\analyzer.exe"

6. Run the analyze command again:

databricks labs lakebridge analyze --debug

ADDITIONAL NOTES

- The analyzer binary is bundled inside the bladespector Python package. When you install Lakebridge, pip downloads the package and extracts the binary. If antivirus scans the extraction in real-time, the file can be removed before the process completes, which is why reinstalling alone does not fix it.
- Make sure you are running Python 3.10.1 through 3.13.x, as required by Lakebridge.
- The Lakebridge documentation and latest releases are available at:
https://databrickslabs.github.io/lakebridge/
https://github.com/databrickslabs/lakebridge

If none of the above resolves the issue, consider opening a GitHub issue at https://github.com/databrickslabs/lakebridge/issues with the full --debug output so the maintainers can assist further.

I personally review the draft for any obvious issues and for monitoring system reliability and update it when I detect any drift, but there is still a small chance that something is inaccurate, especially if you are experimenting with brand new features.
