Password Encryption Failed – Cipher initialization failed

Product Line:

Power SCADA Operations 8.2

Power Operation 2020

Power Operation 2021

Power Operation 2022

Power Operation 2023

Power Operation 2024

Environment:

Starting Runtime
Advance One Line in PowerLogic SCADA

Cause:

Running the Computer Configuration multiple times and repeatedly clicking Register can corrupt or invalidate the local encryption configuration used by Advance One Line.

Resolution:

Solution 1 — Reset Advance One Line user configuration

1. Navigate to:

   C:\ProgramData\Schneider Electric\PowerSCADA Expert\v7.40\User

2. Open the folder corresponding to the project name in use.

3. Open advoneline.ini with Notepad.

4. Delete all entries except the first line.

5. Save the file.

6. Restart Advance One Line.

Solution 2 — Regenerate the cipher configuration

1. Navigate to:

   C:\ProgramData\Schneider Electric\PowerSCADA Expert\v7.40\Config

2. Rename PowerLogic.Cipher.dll.config to PowerLogic.Cipher_old.dll.config.

3. Restart Advance One Line.

Renaming the PowerLogic.Cipher.dll.config file forces the system to regenerate the encryption key for the machine, resolving the cipher initialization failure.
