SketchUp is one of Google's side projects. It is a 3D-modeling program that allows you to create 3D graphics that you can combine with Google Earth real-world locations. A "silent install" SketchUp requires no input from you the user whatsoever. This is not a default option in SketchUp, so you will have to create your own .bat file that tells the installer program which choices to make during the installation process.
Launch "Notepad" from the Windows Start menu. The program is located under the "Accessories" folder.
Copy and paste the following code into the "Notepad" window"
ECHO Installing SketchUp
start /wait googlesketchupwen.exe /a /s /sms /f1%CD%setup.iss /f2%temp%setup.log
del "%allusersprofile%desktopGoogle SketchUp.lnk"
move "%allusersprofile%start menuprogramsgoogle sketchup 6Google Sketchup.lnk" "%allusersprofile%start menuprograms"
rd "%allusersprofile%start menuprogramsgoogle sketchup X" /S/Q
Replace the "X" in line seven with the version number of your SketchUp program.
Click the "File," select "Save As."
Type "Install.bat" into the "filename" box. Browse to where the SketchUp install file is located and save the file to that directory.
Open "My Computer" and browse to the directory containing "SketchUp" and the Install.bat file.
Double-click the "Install.bat" file. This will launch a silent install program for SketchUp using the default options.
