[Fireryyo]

[Attachment 63576 - Click to enlarge] It worked fine in Windows 10 but when I switched to Windows 7 this error occured and after switching to Windows 8.1 it's the same I have deleted all Aegisub folders from Appdata folders too but it doesn't help at all I also have Light alloy and LAV fillers and K-Lite Codec as external video player and encoder too

Edit: I figured it out myself You need to download and install Mediainfo codec from here:https://mediaarea.net/en/MediaInfo
