Hi,
I have trouble with getting adobe pdf reader thumbnail to work in opus. I have x64 system. And i read on this how to fix thumbnail problem with x64 systems http://www.pretentiousname.com/adobe_pdf_x64_fix/index.html
Now my pdf thumnails work in windows but not in Opus. Please some help on this issue thanks.
My x64 Adobe Reader thumbnail fix doesn't work with Opus yet. It's waiting on Opus to support the newer Vista thumbnail API (which was far easier for me to use than the old one).
Support for it is coming...
tanks man, ill silently wait. no hurries.
I understand you guys are talking about 64-bit systems but I've never been able to get thumbnails to work with my W7 32-bit system either. I checked out the info at your site, Leo, but the "fix" appears to be for 64-bit systems only. Either that - or I missed some info and it works for 32-bit systems too.
Is there a way to get thumbnails to work for PDF files in 32-bit systems? As far as I can tell, my settings are correct and everything should be working fine.
Thanks!
Do pdf thumbnails work in Windows Explorer ?
Dopus 9.5.3 is out. Anyone with PDF thumbnails working in x64? My windows explorer shows the thumbs, but Dopus does not...
Read up five posts.
Ensure that my folders are in "Large Icons" view, make sure "Always show icons..." option is disabled.
Uninstall Foxit Reader & Adobe Reader.
Remove Adobe Reader & PDF file type entries from registry.
Ran Unassoc to remove the PDF file type from Windows.
Ran Disk Cleanup to remove Thumbnail files.
Installed Adobe Reader 8.1.2.
Ran xplorer2 32-bit in Thumbnail view. My PDF thumbnails show up both in the file explorer view and in the preview pane (Draft and Native).
Ran Adobe Bridge CS4. PDF thumbnails show up there, too. So, at least I now have 2 effective workarounds to Adobe Reader's ridiculous shortcoming.
Ran the 32-bit Windows Explorer. No problem with PDF thumbnails. Hot damn!
Closed 32-bit Windows Explorer. Opened regular Windows Explorer and browsed to the same directory. PDF thumbnails still working.
Browsed to another folder with Windows Explorer. No PDF thumbnails.
Reinstalled Foxit Reader 3.0 so I don't have to suffer through actually using Adobe Reader. Made sure not to set it as the default PDF reader.
Verified thumbnails in 32-bit Explorer still work. They do. *******.
There you have it. 3 separate workarounds. Maybe Adobe will fix this problem in their next release. Maybe they'll also create a PDF reader that isn't 100mb. Don't hold your breath. Thank me and follow my instructions instead.
The problem is that Adobe haven't provided a 64-bit thumbnail generator and the Windows shell doesn't let 64-bit apps call 32-bit thumbnail generators (at least not directly). Adobe do still provide a 32-bit thumbnail generator, so 32-bit apps can generate PDF thumbnails fine.
Explorer (and the File Open dialogs, etc.) will cache thumbnails, and thumbs cached by a 32-bit process can be read by 64-bit processes (and vice versa), which is how you might start seeing PDF thumbs that you've already generated in 32-bit apps. That's not really fixing the problem because 64-bit apps still cannot generate thumbnails for PDF files; they can only read the cached ones something else made in advance.
My 64-bit Adobe Reader thumbnail fix works by providing a 64-bit thumbnail generator which knows how to proxy calls to Adobe's 32-bit one. Only problem is that it's using the newer Vista IThumbnailProvider API which Opus doesn't yet support (mainly because until now only a tiny handful of things used it).
Adobe could solve all this by finally releasing a proper 64-bit version of Adobe Reader but they seem to have their heads in the sand and fingers in their ears when it comes to 64-bit anything (except Photoshop). 
Opus will definitely get support for IThumbnailProvider in the future, so a solution is coming one way or another. That isn't a completely trivial change and it requires quite a bit of testing, so don't expect it in one of the little bug-fix releases. I expect it'll appear in a point release or major update.
Any update on when this might be fixed? I've had to actually include an 'open explorer' button in opus because of this, not something I'm proud of ( :
IThumbnailProvider support should be in Opus 10 but there's no date for that other than "when it's done" so far.
(I bet that will still be before Adobe pull their fingers out, though. )

Well, they have apparently 'discovered' 64 bit after all. They have just released a beta of a 64 bit enabled Flash Player.
Ok cool, thanks for that Leo, will have to start saving me pennies then.
