# Troubleshooting "Error in reading file Normalization Transformation incorrect version" in Array ACLI

The following error message may be encountered while running an Array data analysis session in Array Analysis CLI (ACLI).

```
{"Timestamp":"2023-03-07T18:05:45.3524710+01:00","Level":"Error","MessageTemplate":"**Error in reading file. Normalization Transformation incorrect version**","Properties":{"SourceContext ":"ArrayAnalysis.CLI.App"}}  
```

The message indicates an issue that is most likely related to the **manifest** file.

Possible root causes include (but are not limited to):

* **CSV and BPM manifest file mismatch**: check that the CSV and BPM manifest file match (if the command requires a CSV manifest).
* **Corrupted files**: make sure that the product files are not corrupted.
* **Regional settings**: make sure that the Operating System (OS) regional settings are set to English US.
