How can I do a silent or network installation on Windows?

Silent Install

On Windows you can install Understand automatically by running the installer from the command line or remotely with the /S command. If you want to specify a different install directory you can do so by including /D=Directory Name. The Directory needs to be the last thing on the command line and can have spaces in the directory names. For example:

Understand-5.953-Windows-64bit.exe /S /D=C:\Extra Tools\SciTools

Details on specifying your license from the command line are here. In most cases you can just run

scitools\bin\<PLATFORM>\und -setlicensecode XXXXXXXXXX





Specifying Legacy Licenses

Floating License

To connect the client to a license server, you can create a file named \conf\license\locallicense.dat with this single line of content:

Server: SERVERNAME 00000000 9000

Where SERVERNAME is the name of the license server and 9000 is the port number

Single Developer License

To install a Single Developer License follow these steps:

Add these lines at the end of %APPDATA%\SciTools\Understand.ini


Create a file called addSDL.reg with:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Scientific Toolworks, Inc.]
