if you register with fake IDM serial key ,sometimes it is accepted and sometimes it is not(which is due to fact the IDM has given its fake keys online mixed within web and as so as you enter those its matches it with its log and blocks it)
many users just find it irrating and some want to try it again so all they do is reinstall windows which is absolutely wrong way to deal with it
all you need to do is delete its log file from windows registry after uninstalling
following is the procedure to do it
1.First open up the Start Menu.
- For Windows xp_ Type “regedit.exe” in the Run Command.
- For Windows 7/8/10 _ Type “regedit” in the Search Box.
2.After opening Reg. editor then go to edit menu or press F3. Then select “Find Next” and a box will open.
3.Enter the name, “Internet Download Manager” and click “Find next.”
4.Delete the registry and if any registry remains then press F3 for checking.
5.Repeat the process of deletion until it shows the message “Finished Searching through registry.”
6.After then close it.
