I have Intex 2.0 TV BOX (TV Tuner) and it's not working properly. I have an installation CD with the application and the driver, I am using Windows 7 operating system.
I have checked the support page and it seems that your product has support for Windows 7 operating system. While trying to install the application and driver, manually navigate the content of the CD and look for the setup package. Right click it and use "Run As Administrator" option when you launch it because running the package without Administrator rights could lead into software and driver malfunction.
This is the known problem when trying to install application for Windows 7.
