So I've been trying to make Sumatra Reader my default pdf reader but whenever I click on a pdf it doesn't allow me to select a default program. The checkbox doesn't even come up. When I right click the options window shows Open With at the very top as if that was the only option. It also does this with .torrent files and I really don't want to know what else it's doing it for.


I've tried going to the Windows 8 PC Settings and setting the default app and going to the control panel default programs settings and setting the Sumatra to default there but in both cases it just doesn't do anything when I select it. It's really annoying and I want to fix it.


I already tried going to my registry and messing with those by following guides I found on google and it's still the same. I think my ccleaner's registry cleaner or my iobit scanner messed with the file associations and now they're being unresponsive. Need some help fixing it.

Hi Hyperman :)

You could try to reset the default file associations using Windows Repair AIO, then seeing if it unlocks the rest. Also, you should never, ever use Registry Cleaners. These programs are dangerous to use since they can break your Registry, making your Windows unbootable, plus they won't boost your system performance at all. In fact, there's no statistics or studies that shows that Registry Cleaners are good for your system, nor that it help increase it's performance.
