How can I uninstall this "Media Info" from popup menu ?
Launch MediaInfo, Preferences, uncheck "Explorer extension".
There is no "MediaInfo" programme in my system (Windows 8) !!!
How can I launch it ?
I have it in popup menu only !
You installed MediaInfo... So it is present (in start menu if you installed a start menu and in the start screen).
from your questions, I think you don't use a program developped by me, but a "MediaIfo" developped by someone else (e.g. klite codec pack), and you did not expect to have such tool on your machine. I do not provide support for tools not developped by me, even if my name is written in this tool without my consent.
In the case you have the application from klite, you can install official MediaInfo then uninstall it, it will remove the menu from klite codec pack. You can also uninstall klite codec pack.
Please, take a look of this image ...
Now I'm trying to download official MediaInfo (to install and then to uninstall it ...)
I installed it. Then I unchecked the flag "Explorer extension" and uninstalled it.
Program was removed from my system.
Thank you !
Who were that bad guys which bring such soft in my system ?
