The UAC (User Account Control) recognizes that a program is trying to be installed and wants to make sure you are aware of this and if you wish to allow these changes. This generally occur when using an Administrator account.
You can try changing the account settings.
There are four settings:
1. Always notify me.
2. Notify me when apps try to make changes to my computer.
3. Notify me only when apps try to make changes to my computer.
4. Never notify me.
To make changes you will need to access the User Accounts. To access the User Accounts do the following.
Press the Windows key and the R key to open the Run box.
Type or copy and paste msconfig in the Run box, then click/tap OK.
When System Configuration opens click/tap the Tools tab.
Under Tool name click/tap Change UAC Settings, then click/tap the Launch button.
You will now see the UAC Control Settings. You can click/tap on the slide bar to move it up or down to change the level of the settings.
There is a security issue which needs to be recognized if you lower the settings. The UAC alerts you to any programs that might be trying to change your computer, including viruses and malware links you may have accidentally clicked on. If you disable the UAC completely and you're using an administrator account, any program that runs on your computer, including viruses and malware, will automatically have access to make changes to your PC. For this reason it is not a good idea to turn off the UAC. You can try the lower level settings to see if this helps. You may want to try using a regular user account apposed to a admin. account.
