1) Download Google SketchUp v7.1.4871 via either of the following links:

http://dl.google.com/sketchup/GoogleSketchUpWEN.exe
http://www.filehippo.com/download_google_sketchup/

2) Run the SketchUp installer, wait until the "Welcome to Google SketchUp..." dialog box appears and then find the extracted GoogleSketchup7.msi in your %Temp% folder.

3) Once you have the .msi, close the SketchUp installer and then use the included transform to deploy it. For example... 

msiexec /i "GoogleSketchUp7.msi" TRANSFORMS="GoogleSketchUp7.mst" /qb!

This will create the "%ALLUSERSPROFILE%\Application Data\Google" folder during installation thus allowing restricted users to run the program successfully.

Note. Leave the 'CommonAppDataFolder' in the same folder as the .msi and .mst.
