This message can appear during installation for a variety of reasons, so several potential solutions are available.

Installers downloaded from the Internet are blocked
Right-click on the installer, choose Properties and then click the Unblock button.
Anti-virus or anti-malware software is blocking the installation
Try disabling this during the installation.
Security Policy is preventing installation
With some operating systems, you can open the Group Policy Editor to do this (gpedit.msc). If you open this editor, in the left pane you will need to expand Computer Configuration, then Administrative Templates, then Windows Components, and finally you will need to click on Windows Installer. Now in the right pane you will need to double click Disable Windows Installer and change the setting from Enabled to Disabled.
With operating systems that are Home versions the Group Policy Editor is not available which would require you to edit the policy in the Registry. Here are steps for editing the registry:
- Open the Registry Editor
Windows Vista or later

- Type REGEDIT in the text box directly above Start and press Enter
- Click Start and click Run
- Type REGEDIT and click OK

To do this, click the triangle or plus sign next to each item listed until you get toInstaller then click Installer in the left pane to display its values in the right pane
- Right click DisableMSI (right pane), choose Modify, and change the value to 0
- Close the Registry Editor
