0.92: XnViewMP not showing webp images when opened from Windows Explorer

Post by anonymous_user » Sun Jan 06, 2019 6:53 pm

XnView: MP 0.92 - 64 bit
OS: Windows 10 64bit

If I try opening a webp file from with Windows Explorer, XnViewMP will open up with a blank view and no image. However if I use the XnViewMP browser, I can go to the webp file and it will open just fine that way.

Effect: image not shown

To reproduce:
1. Set XnViewMP as default application for webp files
2. Open Windows Explorer and open a webp file

Actual behaviour (bug): XnViewMP opens but doesn't show the image

Expected behaviour: XnViewMP should show the image

How do I check the registry association? I already tried settings another app as default and then changing back to XnViewMP but it didn't help.

Also I tried deleting my config files so XnViewMP would be at default settings but that didn't help either.

Thankfully .webp files are not extremely common so this isn't a huge deal for me.

Yes if I drag and drop a webp file onto the XnViewMP window or shortcut then it opens fine.

I'm having the same issue (MP 0.92 & 0.93) it can open .webp from xnview browser and has thumbnails, but can't from double clicking the files in windows explorer (it just opens the xnview browser in default folder).

btw how to add webp thumbnails to windows explorer?

I'm not sure what am I looking for in there, give me an example of how should it look like and which key to look for or maybe as a .reg file.
the files do claim to be associated with xnviemp in their info window.

I have the same problem since 2-3 weeks ago. The entry in registry is correct.

Please fix it!

Same here v0.93.1 64bits
With XnView Classic no problem, but with XnView MP, when you open a .webp file with "Open With.." or associating the file, the program runs, but does not load any image.

In the "Windows 10" registry when it is associated with XnView Classic it appears:
Image
But if you delete the ".webp" and ".webp_auto_file" registry entries when you associate it with XnView MP:
Image

Can that "%1" make a difference? I've tried adding it with:
"C:\Program Files\XnViewMP\xnviewmp.exe" "%1" but even if you delete the entire string ".webp_auto_file" from the registry, keep doing the same thing, the program runs but does not load the image.

DP:
When you click on "Settings>Intergration>File association" Windows 10 tells you "To change the default applications, go to Settings> Applications> Default Applications." but XnViewMP is already associated as the default images program.

Ok, I don't know what I did exactly, but I fixed it!
Surely someone can simplify the steps and find simplest solution.

What I did was something like:
1. Run "C:\Program Files\XnViewMP\Associate files with XnViewMP.exe", click on [Unregister from XnViewMP]
2. Open RegEdit "Computer\HKEY_CLASSES_ROOT" and delete the associations that were marked in the program "Associate files with XnViewMP.exe" on mine reg were 4 or 5 assigned files (.png .jpg .bmp .gif .. something like that)
3. Run XnViewMP normally
4. Go to Start Button> Settings> Applications> Default applications, and set the default Windows as a photo viewer, then.. select as photo viewer "XnView MP"

If someone with the same problem can solve with this way or simplify it would be appreciated.
Anyway now in the windows registry if it has been associated well and what I described in my previous post appears:
"C:\Program Files\XnViewMP\xnviewmp.exe" "%1"
(And I have not added it, it has been added automatically) :D

I've managed to make xnviewmp view open the file when doubeclicking a .webp by adding "%1" at the end of the link in ..ROOT\webp_auto_file (it is without a dot for me btw)
But the thumbnails are still showing the default icon, instead of the image.

I've noticed that the same issue applies to .svg
