XYplorer Beta Club

I have this problem also ... mouseover on an .AI file shows a red popup infobox with "Cannot Decode" :veryconfused: I tried running the below script, and a couple variations, but it had no effect ... Run this from address bar extlist("thumbs64", "ai.eps.svg", "a&qu...

Oh that's good. So I can remove this sentence in my FAQ? In case you are using Adobe Acrobat Reader: Uninstall it. Or change it to: "If you keep Adobe Acrobat Reader you might need to apply this registry edit." I don't have Reader. I have Acrobat Pro, and a workflow built on it, so I don'...

This usually helps people where it does not work out of the box: https://www.xyplorer.com/faq-topic.php?id=PDFthumbs Install the free PDF-XChange Viewer. If you are using PDF-XChange Viewer and there are still no thumbnails add this key to your registry (only do it if you are experienced and know w...

I still get the black thumbnails on an all-new laptop, all-new OS Win 10 Home (bleh), all-new Xyplorer 17.20, various different thumbnails sizes (the presets, or custom sizes). The "refresh selected thumbnails" workaround is still good ... just an extra step. For the record, I still totall...

Also tried SageThumbs and FastPictureViewer, but still get black thumbnails for PDFs.

I installed http://www.win7pdf.com/pdf-preview.html and it might have fixed the black thumbnails. I'll try it on all my other machines and report back. I still saw at least one black preview on mouse-down. And before & since installing PDF Preview, some of the previews on mouse-down just failed ...

Oh goodness ... now I am getting gigantic floating black boxes from the "Preview On Mouse-Down" feature! :shock: ... even on PDFs that have proper thumbnails! (For the cherry on the sundae, XYplorer Help.pdf has a black thumbnail and black preview on mouse-down.) I am not having a good wee...

There is some noise on the interwebs about black thumbnails for PDFs in 64-bit Windows. But one of my machines is 32-bit, and it has the black PDF thumbnails.

I think it's a variant of bubonic plague.

It's NOT doing it on one of the other computers at that same day job. Now, what in the heck is different about THAT computer, I wonder? Same versions of Windows & Acrobat that I have on my home computers ... what could it be ...

Yeh ...

Just to make sure it's not something that *I* am doing on *my* computers, I installed Xyplorer 16.10 on a computer at one of my day jobs. This computer's OS is a special edition called "Windows Embedded," which I've never seen on any other machine. It does not have Acrobat XI Pro as mine b...

Maybe ... so I uninstalled, manually deleted remnants from hard drive & registry, rebooted, reinstalled, rebooted again ... but the black boxes still occur. I remember an "Adobe Cleanup" script somewhere ... maybe I should try again, and use that script. It's supposed to get rid of &qu...

Nah, the file-size idea was a red herring.

I just don't see any particular causation for the black boxes. It's really weird.

Just noticed, in a folder with 13 PDFs, only two of them thumbnailed, and they were the smallest files (72kb, 260kb). The rest were black boxes (592kb thru 4,536kb).

I wonder if filesize is causing the thumbnail operation to time out per item, maybe?

"Refresh thumbnails" worked as usual.

So I added a "user button" on my toolbar, and gave it command #501. Now with one click, I make the black boxes into proper thumbnails. So far, seems to work every time, at any thumbnail size, and it's very fast. This is a better solution (for me) than installing a separate default PDF prog...
