Problems With Windows Installer?

It seems like your user profile is corrupted. Navigate to Programs and Features and check whether you have Itunes Malware Bytes and stuff listed. If not try running the setup for each of these programs. If still no go, then run the setup for each of the files after creating a new user account. Make sure you are a member of Administrators and Power Users group. Delete the old user profile and restart your terminal to save changes. Now install the setups again and you are up and running again.
