If you received the install media you can copy the deployment files from the install directories included on the media. If you did not receive the media you will need to extract the install files into a directory using a utility such as 7zip to extract the compressed executable file. You can now copy the deployment files from the media or the extracted directory into your desired deployment directory. 

Executable file is an Installshield file. So using methods familiar with installshield will work fine.

If you received the install media you can use the included .iss response file from the installer. If not you will need to record your own response file using the /r switch as documented for Installshield. The default name for the recorded file is setup.iss and is stored in the windows directory during the recording process. It can also be located in the windows\system32 directory. If you wish to specify the name and location of the .iss file you can use the /f1 switch in conjunction with the /r switch to specify the name and literal path of the response file. Verify that you do not use a space between /f1 and the absolute directory. Example:setup64.exe /s /f1"C:\Temp\Setup.iss"  After you have performed the record process copy the .iss file into the desired deployment directory. 

The silent install command line is now run using the following syntax.

setup64.exe /s /f1"setup.iss" /f2"c:\envi_log.txt"

/s for silent

/f1 to specify the response file

/f2 to specify the installer log file
