Geo SCADA Installation Error: "The File or Directory Is Corrupted and Unreadable"

During the installation or upgrade of Geo SCADA, the process may fail with the error message: "The file or directory is corrupted and unreadable."

As the error message suggests, the ISO image is either corrupted or incomplete, meaning it does not match the full content of the original file. This can happen for a variety of reasons, including interrupted downloads, disk-related problems, or file system errors

To ensure the integrity of your ISO file, there are several methods available to verify whether it has been downloaded correctly. One of the most reliable ways is to generate and compare a SHA-256 checksum.

Below are the steps to generate a SHA-256 checksum using both Windows Command Prompt and PowerShell, so you can verify the integrity of the ISO image.

Command Prompt:

1. Open Command Prompt
   Press Windows + R, type cmd, and press Enter.

2. Navigate to the File Location
   Use the cd command to change to the directory where your ISO file is located.
   For example:

   cd "C:\Program Files"
   

3. Run the Checksum Command
   Enter the following command, replacing <file_name> with your actual ISO file name:

   certutil -hashfile <file_name> SHA256

   Example:

   certutil -hashfile "Geo SCADA 2023 Update Mar 2025 (86.9210.1).iso" SHA256

4. Review the Output

   The command will generate and display the SHA-256 checksum of the file.

Powershell:

1. Open PowerShell:

   Press Win + X and select "Windows PowerShell (Admin)" to open PowerShell with administrative privileges.

2. Generate the hash value:

   Use the Get-FileHash to generate the hash value of your ISO file. For example, to generate a SHA-256 hash, use the following command:

   Get-FileHash -Path <File Name> -Algorithm SHA256

   Example:

   Get-FileHash -Path "C:\Program Files\Geo SCADA 2023 Update Mar 2025 (86.9210.1).iso" -Algorithm SHA256

3. Review the Output
   The command will generate and display the SHA-256 checksum of the file.

Compare the Checksums: Match the generated checksum with the one provided by the official source here:

• ✅ If they match, your ISO file is not corrupted.
• ❌ If they don’t, the file may be corrupted or incomplete—and should be re-downloaded.

As shown above, both generated SHA-256 checksums match the one provided by the official website. This confirms that the ISO image is complete and not corrupted, and it can be safely used for installation.
