★★ZWCAD fails to launch, error message “OLE initialization failed. Make sure that the OLE libraries are the correct version” occurs

Issue:

ZWCAD fails to launch, and an error message “OLE initialization failed. Make sure that the OLE libraries are the correct version” occurs.

Causes:

The .NET Framework components needed to run ZWCAD are not installed or the installed version is incorrect and causes the failure to launch ZWCAD.

Solution:

1. Right-click the installation package and extract it (if there is no extract application on the computer, just install one).
   
2. Follow the picture below, and open the prerequisites folder in the extracted package, which contains the installation package for .NET Framework components.
   
3. Install the .NET Framework components in the folder, and launch ZWCAD again after the installation.
   Note:
   In some cases, it’s because there is something wrong with the .NET Framework components that are already installed on the computer. Please uninstall them in the control panel, then use the files in the ZWCAD installation package to install them according to the steps above described. Due to the .NET Framework components being included in the Win10 and later systems, it cannot be manually installed.
