Cctvbox can not be installed on Win7 system solution

I am using the IE browser that comes with the Windows 7 system. When I open the CCTV website and prepare to install the live plug-in, IE always prompts that the memory cannot be read but cannot be installed. How can this be solved?
This may be installed in the system plug-in interception tool, blocking the installation of the CCTV live plug-in, you can close the plug-in interception software, and then install.
In addition, please check IE's own plug-in blocking function. Normally, when you open the page where you need to install the plug-in, a yellow prompt bar will appear on the top of the browser. Just right-click the prompt and select “Allow installation”. Related items can be downloaded or installed directly at http://t.live.cctv.com/ieocx/CCTVRegOcx.exe.
In addition, CCTV launched the client software, you can download the CCTVBOX program from http://t.live.cctv.com/cctvbox/cctvbox.exe. After installation, you can watch CCTV channels directly through this client program. The show is gone.
