Hello, According to your problem description, I suppose that you should be using a standard account instead of the build-in administrator to install and uninstall programs and getting the User Account Control (UAC) popup box. User Account Control (UAC) makes it much easier to keep users out of the Administrators group. With UAC, users will still be able to run their applications, but they won't be able to make changes that might negatively affect their computer, such as changing system settings or installing new applications. The control that UAC provide administrators will keep client computer much more stable. For your information, you should refer to the following Knowledge Base article. How to use User Account Control (UAC) in Windows Vista http://support.microsoft.com/kb/922708/en-us For the current situation, please enter the administrator password, or press Enter on the keyboard when you are prompted for an administrator password or for a confirmation. Note: if you dont know the administrator password, feel free to contact with the person who installed the OS on the computer. If the above step could not work, it is appreciated if you could answer my following question. 1. Right-click the program installation file and select Run as Administrator, enter the administrator's password, are you able to run the program setup wizard properly? 2. Does your computer work in the domain? Do you set some local group policy on the computer? 3. Log off and login the computer with the build-in administrator account, test the issue again. Feel free to let me know the result!
