Allowing Installation With Security Software
In order to install MSC Apex Generative Design, the application and its lockserver must be allowed to execute by any security software on the system. MSC Apex Generative Design is whitelisted with Symantec, but users with other security software must add exceptions that allow the MSC Apex Generative Design lockserver to run. If these exceptions are not made, the security software will prevent MSC Apex Generative Design from installing.
If a security error occurs during Apex GD installation, users should manually add Apex GD installation folder to their security software's exception list and then start the lock server using lsconfig.bat. lsconfig.bat is located at :
"<INSTALLATION_FOLDER>\leaf\Services\EOM\WIN8664\bin\lsconfig.bat".
