Q. How can I install InterMapper or IMRA in silent mode on Windows?

A.To run the install in silent mode, record the sequence of clicks you would use in interactive mode.

To Summarize:
Under DOS command, type this command to create the response file to be used in silent mode
<InterMapper install.exe> /r /f1<fullpath of the .iss>/Install_Setup.iss

To install InterMapper in silent mode, type this command:
<InterMapper install.exe> /s /f1<fullpath of the .iss>/Install_Setup.iss

Note: no space between /f1 and .iss fullpath

InterMapper_RemoteAccess_Setup_556.exe /s /f1C:/Install_Setup.iss
