Missing admin rights at sofware installation...
If you get the error message "...administration rights required...", your computer user account doesn't have sufficient rights to install new software.
If you are working on a company computer, contact your IT specialist to log you in as an Administrator so that you can install the software.
If you are working on a home computer, you will need to either log off and log on as Administrator or set your current rights with Administrator privileges that will allow the installation routine to run correctly. Most home computers' default settings will automatically have administrative rights and you should not have any problems.
