License Error: Initialize() Fails to Execute
If you encounter the following error when running a DW SDK project, it indicates that the licensemanager_cli.exe is not located in the correct directory:
- ### Step 1: Restart the Computer
Sometimes a system restart can resolve the issue. If the problem persists, follow the steps below.
- ### Check 1:
If you have previously installed older versions of DWSDK, DaoAI Vision Pilot, or DaoAI Inspectra, those software versions might include outdated License Manager files. Due to environment configuration issues, the system may be using those older License Manager files.
- #### Solution 1:
Search for license_manager on your system disk and remove any instances of licensemanager_cli.exe and licensemanager_gui.exe outside the DWSDK installation directory. Retain only the files located in the bin folder under the DWSDK installation directory.
Example:
C:\Program Files\DaoAI World SDK\DWSDK\bin- ### Check 2:
Verify that the DWSDK installation directory contains licensemanager_cli.exe and licensemanager_gui.exe. Ensure your system's environment variable PATH includes the correct DWSDK bin path, such as:
C:\Program Files\DaoAI World SDK\DWSDK\binIf the variable is configured using
%DWSDK_PATH%/bin, ensure%DWSDK_PATH%points to the correct installation directory.- #### Solution 2:
Correct any erroneous system environment variable configurations and ensure the path includes:
C:\Program Files\DaoAI World SDK\DWSDK\binandC:\Program Files\DaoAI World SDK\DWSDK\3rdpartyand is at the top of the path- ### Check 3:
Delete the DaoAI folder in the Windows
%temp%directory and re-run the SDK program.
- #### Solution 3:
If the issue persists, the model being used may be corrupted. Retrain and export the model to ensure it is valid.
