Sketchup Installtion Issue

Dear All,

I have downloaded SketchUp Pro (SketchUpPro-en-x64) on Windows 7 Ultimate. When I select “Run as Administrator” on this file, it extracts fine and then shows message “This installtion package could not be opened. Verify that the package exists and that you can acess it, or contact the application vendow to verify that this is a valid Windows Installer package”

Please help in resolving this issue.

Thanks and Regards,
Vinayak
