This is the most common reason as to why you are unable to play AVI files in Windows Media Player. However, it proves that the camera is working and recording just fine.If you have a Windows 10 computer, AVI files will play only on “Films & TV” application and not on WMP. I already had the K-lite mega codec pack install on my PC and I haven't come across any other file type that I haven't been able to play since I installed it.Ĭurrently, the only way I can actually play these files is on my mobile which is a real pain. Furthermore, I can't connect the QVR client at all no matter what settings I use and I have followed the advice of changing my local intranet settings to no avail. Also, when I try to playback from the SS interface, I just get the same message to install QMon.exe again even though I have done this several times and followed the instructions about shutting down Chrome first to the letter. I have now done all of these things and I still can't play the AVI files on WMP (or any of the other 3 video apps I have).

I have looked at this forum (and elsewhere) and gathered that QNAP uses its own modified codec and the advice seems to be to install this either via the QVR client, using the QMon.exe that is suggested by the SS playback or using the codec tool on the support website.

However, since I last used it, I have upgraded to Windows 10 and I now find that I cannot play the recorded AVIs files back on my PC.

I previously had this set up successfully so I didn't have to change any settings at all. I have recently reinstated my Foscam FI8918W as a surveillance camera on my QNAP TS-451.
