[Installation] How to reinstall CIVIL


I am curious about how to reinstall CIVIL after deleting it.



If essential modules required for running the program are missing or damaged during the previous installation of CIVIL, all program-related data and logs must be deleted before reinstalling. Alternatively, to install a new version, you need to remove all previous versions of the program.

 Additionally, during the installation process, the necessary modules for program operation or execution may be missing or damaged due to security issues on the user's PC. To prevent this, it is recommended to disable antivirus software and firewall before installation and proceed with Windows updates. Windows update is a good way to fix system errors, including computer security issues. Although it is difficult to determine if specific errors that occur during Windows updates are directly related, it has a positive effect on resolving overall security issues and error states in the system.

 Lastly, it is recommended to close and delete all other applications, including Microsoft Office that are linked to MIDAS program before reinstalling. Running the application can interfere with the MIDAS program installation process, so it is better to close all applications before proceeding.


1. Uninstallation of CIVIL

Even if you install the program using a different method or process than the one we provided, it may not cause any problems when using it. However, various errors can occur at any time if the program is executed in an environment where the operating conditions are not fully established. In such cases, there may be an inconvenience in having to repeat the process of uninstalling and reinstalling the program. We hope that you will follow the above procedure when you first install it without any inconvenience.
