MKV MediaInfo not showing in Win10 details pane Empty MKV MediaInfo not showing in Win10 details pane

Hello
I am here to report a problem with K-Lite Codec Pack, I believe it is mainly related to Icaros but I am not certain.

This issue is related to the details pane of Windows not showing MKV details such as Duration, Resolution, Video/Audio Codecs etc.

I have been running K-Lite for many years on this machine with no issues, until the version v14.7.0 (Mega), at the time of updating this machine's copy of
K-Lite to 14.7.0 I was running Windows 8.1 and before it would display all these things in the details pane, but after updating to 14.7.0 it only showed the filesize,
this didn't worry me as I was updating to a clean Windows 10 install soon anyway, but this issue carried over to Windows 10 as well. I tried installing this version of
K-Lite on another machine and the details where there and there was no issues, so I decided to reinstall windows 10 fresh yet again on the machine that was giving me the issue.
This time K-Lite was working perfectly, with the same 14.7.0 that was previosuly giving me issues, as it had for the previous 5 years with the other versions of klite, showing all the details of the
mkv file.

Fast foward to now, I just updated to 14.7.5 and it now has again reverted to just showing the file size.

I am using Windows 10 Pro x64 1803 on both mentioned machines, and both have been updated as of today (not to 1809 however)

So far I've tried the following solutions on this current install:
- Clean installing K-Lite Mega 14.7.5 (Didn't work)
- Clean installing K-Lite Mega 14.7.0 (Didn't work)
- Clean Installing K-Lite Standard 14.7.5 (Didn't work)
- Installing a version I remember to work (Mega 14.5.5) (Didn't work)
- Install Icaros Seperately (Didn't work)
- System Restore (Did work for a little bit and brought it back to the way it was before I updated to 14.7.5, but after a reboot it went back to not working, this restore was for 21.Feb so not long ago)

I hadn't changed any system settings within that time and Windows 10 Settings wise both mentioned machines are setup the same way, I did find however that whilist the other machine will give the option
to quick update, this machine with the problem will try to go through the whole install process again, even though it is an update.

I do have some other machines with the same version of K-Lite and Windows that also do not have this issue, so it seems isolated to this machine and only recently as of this year

Thanks

Check if this Registry key exists:
HKEY_CLASSES_ROOT\SystemFileAssociations\.mkv
It should have values FullDetails, PreviewDetails, InfoTip, and ExtendedTileInfo.

And this key:
HKEY_CLASSES_ROOT\CLSID\{0C08E3BB-D10B-4CC9-B1B3-701F5BE9D6EC}

And this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PropertySystem\PropertyHandlers\.mkv
(default) = {0C08E3BB-D10B-4CC9-B1B3-701F5BE9D6EC}

And this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved
Should have value {0C08E3BB-D10B-4CC9-B1B3-701F5BE9D6EC}

And this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Icaros
Excluded Properties = .avi;.flac;.mp3;.wav

I am not sure why this got broken for you. Perhaps access permissions on certain Registry keys are wrong.

Icaros also handles properties of a few other file types like .flv. Try renaming one of your .mkv files to .flv to see if Icaros at least partially works.

All of those registry entries exist and were correct

I tried changing the extension to flv on two files, nothing changed, I did try AVI/MP4/MOV/M2TS and they all changed slightly to show a rating property (those stars)

Could it be possible that some of the settings on the registry key itself under 'data' part may be wrong

Just a quick update, I decided to delete the registry entries that you listed and then I took a backup of the same entries of the other machine that worked and restored them on this one before rebooting, it now works perfectly again, and even went to update to 14.7.5 and it did quick update now too and still works

Thanks for listing the registry entries, they were of great help

Did you happen to make backups of the keys on the broken system? It would be interesting for me to analyze what was incorrect.

I'll be honest, I didn't think to backup the individual registry entries, but I did backup my whole registry. However this did not copy completely, but after some effort I have been able to get my files back for the most part. I don't know if this will
recreate the issue fully but there may be something here.

https://www97.zippyshare.com/v/7SKrhDLm/file.html

This file should contain
Icaros/PropHandler/ShellExt (these were extracted using Registry Workshop)
CLSID (extracted with Windows' RegEdit)
SysFile (extracted with Windows' RegEdit)

The ones that were taken with Registry Workshop where saved in the original backup, I got CLSID after trying to import it with RegEdit and the same with SysFile, I believe however SysFile may just be a stock windows install one. I couldn't do them all with RegEdit as restoring the full backup pretty much bricks the Virtual Machine I used to get them back. This was the best I could do at the moment, hopefully it has some use.

Also, whilst trying to recover these, I did delete those registry entries again like last time but didn't replace them and reinstalled the 14.7.5 Codec pack, and it seems to have installed just fine without issue, so it is definitely an odd issue. If the issue ever comes up again, I will post new files I guess

I don't see anything wrong in the reg backups.

On Windows 8/10 this key is also needed:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PropertySystem\SystemPropertyHandlers
With '.mkv' = {0C08E3BB-D10B-4CC9-B1B3-701F5BE9D6EC}

I talked to the Icaros developer and the problem was most likely 'wrong' values in
HKEY_CLASSES_ROOT\SystemFileAssociations\.mkv

Icaros only changes the values if they are equal to Windows default values. This to prevent undoing any customizations someone might have made. I assume you didn't do that. Did you install/update any other software shortly after the system restore that might have changed something?

Yes that is correct, I never changed any of the settings there. Well, I did system restore twice, the first time, I went to update K-Lite straight away, where it broke again, and then the second time, the only update was a Windows Update, any other software remained the same

It does make somewhat sense as it seems the default Windows information on the details pane when I did the Virtual Machine install, had more information such as resolution and bitrate whereas mine only shows the file size and date modified, so somehow the Windows version was alright (to have worked in the first place) but then stuffed up somewhere along the way. My software setup hasn't changed in a few years asides Windows 10
