[Question] New Installation

[03302024]

I installed version 2.0 on Window 11 23H2. I setup the options as the image on home page. I don't see any thumbnails at all.

Is there any dependencies missing on my computer? or any other thoughts you might have?

Windows keeps a cache of thumbnails, and this cache needs to be wiped in order for new thumbnails to appear. The cache includes the various "blank" thumbnails which Windows is showing.

The "Disk Cleanup" tool [which is part of Windows] is the best way to wipe the cache.

Once run, when you next view your Explorer pane in Medium / Large / Extra Large icon mode, you should see the new thumbnails get generated. Note that "Small icons" mode doesn't give you the thumbnails.

As far as I know, Microsoft doesn't make it possible for a program like DarkThumbs to force a cache wipe, to my frustration.

Hope that helps!

Thank you for the explanations. Sorry to say still not working for me.

I downloaded two sample files from here: https://filesamples.com/formats/djvu "sample2.djvu" doesn't show any thumbnails "sample1.djvu" causes repeated Windows Explorer crash (be warned)

Sample file from here also causes repeated Windows Explorer crash (be warned) https://commons.m.wikimedia.org/wiki/File:Example.djvu

I'm very sorry to hear that! I'll check out the links you provided. I don't have a large library of djvu files, so they'll be helpful.

My own recent testing was only on Windows 10, I'll spin up a Windows 11 test environment and check that too.

Thank you for looking into this.

I tried DarkThumbs 2.0 with Windows 11 23H2, and the three files you linked to, and here's what I got:

So, sorry to say, it works fine for me [at least with the DarkThumbs settings I show]. Both of the "FileSamples" files worked fine. "Sorry to say" because it doesn't fix it for you.

"File_Example.djvu" can't be read by DarkThumbs, nor can it be read by the "DjView" program [which uses the DJVU library used by DarkThumbs]. So I'll have to report that to the DjVuLibre library maintainers.

My thanks for trying DarkThumbs and trying to diagnose the situation!

You might want to check to see if the "Microsoft Visual C++ 2015-2019 Redistributable (x64)" is installed on your system. Here is a screen cap from the "Add or Remove Programs" display on my system:

Note you'll want the "x64" version, not the "x86" version.

Yes, I have that installed.

Thanks for the efforts. I guess I will check the app out again when DJVU engin is updated.
