Couple of weeks ago, I shared IDM 7.2 Portable. But it has some features disabled. But this IDM 6.21 has all features enabled. And it's pre activated!
As I always said, IDM is a very easy to use download manager. It's the most trusted downloader all over the world. Follow the instruction below:
Download IDM 6.21. (It's completely free of spam, virus or ads)
It's a zipped folder - unzip it first.
Now open the folder and double click on IDMan.exe to run IDM.
Now start downloading!
