Step by Step Directions for Techs
Silent install isn’t working, but I need to automate this!

Never fear, a script is here (kinda).
Recently I was working to automate the installation of a poorly written program. For the life of me this thing would not install quietly. Repackaging it failed and I was running out of time. I choose to install the program and pass the appropriate keystrokes to it.
Note: This is not advised when rolling applications out if the user is at the keyboard. One click to another application and this all goes haywire.
So what I did what create an install.vbs script that looks a bit like this:
Set objShell = WScript.CreateObject(“WScript.Shell”)
‘This pulls up the “Setup” window as the active window
Do Until Success = True
Success = objShell.AppActivate(“Setup”)
‘Takes a bit before the application can take inputs. This is 6 seconds
‘This clicks the install button
‘It takes a little bit to install it
‘Close configuration window by pressing Alt-D-E
Once you have that, you launch the setup program (you can do that in this script or in another one. However, if you do it from a batch file, you need to use a start command (otherwise it waits for the process to finish before moving on):
start “” “%~dp0setup.exe”
start “” “%~dp0install.vbs”
Note: The %~dpo is a shortcut that uses the current directory it is being run out of instead of hard coding the paths.
As you can see, there is a bit of timing you have to get down. That is just trial and error. I used a virtual environment and snapshots to get the it working so I could always install on a “clean” system.
If there are other keystrokes you need, here is where I got them:
