Window: Installing software failures and running as administrator
Time to upgrade a program other than Silverlight and Java and iTunes, you may need to RUN as ADMINISTRATOR. With bigger, more invasive programs, you need to run as the administrator on your PC to give permission for this newer version to fit into your system all the way. If not, you may end up with those messages after a while, “Failed to complete.” “Fatal error on installation.” “Incomplete installation.” and similar. Try right clicking and running as administrator.
