No preview in Windows explorer


In Windows explorer, if I enable preview panel

Sumatra don’t display any content.
Error : preview not available

Tested with Sumatra 3.1.2 and Win 7 x64 Pro edition


Work fine as intended here on Win 7 x64, double checked by reinstall


Your version is 3.2.1 Pre-release
I mention to be in 3.1.2
I don’t find this parameter in options


Especially for you I unistalled see “no preview” in right hand preview pane at top
then ran 64 bit 3.1.2 installer from all works as expected

NOTE it only previews PDF not a “link” to a program such as VLC


OK works fine now.
Annoying to not have this feature into Sumatra directly.
If you forget to enable this option when install, you must re-download to do it.
