and iside the ZIP file I actually found some Opus help files, which leads me to believe there is some connection.
I run the program and behold, thumbnails are working in Explorer, but they are still not working ion D Opus.
Am I missing something? Do I need to restart the computer (I have a temporary issue that makes each restart a 20 minutes affair so I'd rather not until this is fixed)?
What is the best way to display PDF thumbnails in Opus?

Thank you both. I wasn't aware of the sorry support adobe had of 64bit systems.
It is just amazing to me these companies don;t have someone that would spend 5 minutes a week predicting the sate of computing 2, 5 or 10 years in the future.
I remember back in 1999 forecasting that inside of 3004 all computers and OS would go 64bit and that by 2010 32bit computers would be a distant memory. Based that on the fact that RAM requirements were doubling every 2 years or so and that by 2004 we would have been maxed out on RAM and the only viable solution was to go to 64bit.
I was both wrong and right. Right in the requirements, wrong in the ability of MS and companies like Adobe to get on with the times and their user's needs.
I have recently been doing some work on computer languages for a bunch of academics.
Their view is that no one has really started to address the real challenges of multi-core processing. To quote my version of the expert view on writing for multi-core processors:
While academics aren't always up with what is going on in the real world, I'm inclined to believe this one.
I am not surprised. The major applications do not take advantage of multicore processing. In my own testing, comparing processing speed in photoshop 32bit against Photoshop 64bit on Win7 working off the same dual booting machine showed the 64bit application about 10 seconds slower over a 3 minutes PSD action. It makes no sense and can only be attributed to poor design of the 64bit application which incidentally had access to about double the RAM of the 32bit.
However, I believe Videogames are currently the type of software that takes more advantage of multicore CPUs. I am a Sim Racer and some sim racing titles (their engines) take advantage of multicore architecture more than their business counterpart. And some of these titles are quite old by now.
64-bit code isn't always faster than 32-bit code, even if it is well-written (and well optimized by the compiler, etc.). It can be, but sometimes it's slower, too. For example, 64-bit code must use larger pointers (8 bytes instead of 4) and if that extra space usage means the difference between a cache hit and a cache miss (multiplied by millions of times) it can slow things down.
OTOH, 64-bit code can use more registers, so it can also run faster than the same 32-bit code. The speed issue is neither here not there, really.
It makes sense to use 64-bit versions of apps if you want them to be able to access more than 2-3GB or if you need them to interact with other 64-bit components (like, as is the case with Opus, the Windows shell, i.e. Explorer and shell extensions such as context menu items added by other programs) and/or see the "real" view of the filesystem and registry (instead of the fake view that 32-bit processes see) without having to bend over backwards (which can confuse the app and/or its plugins if you're not very careful).
Other than things like that, 64-bit versions of apps are not necessarily better (or worse) than 32-bit versions; it will vary from app to app (and also on different hardware or different workloads given to the same apps).
Yep, and as of January 2012, 64-bit support is still non-existing for Arcobat. Note that Acrobat also will not install a 64-bit iFilter plugin, even though one exists for download at Adobe, but that one's half-broken anyway.
For those of you who want/need proper 64-bit support for PDF files, there are two items I can recommend:
For PDF thumbnails (plus thumbnails for many other file types as well, I use MysticThumbs, see here: http://mysticcoder.net/MysticThumbsHistory.html. This one is not free, unfortunately, but it's the only solution I have found that really works well.
I don't know how attached you all are to using Adobe but me personally I try to stay as far away from it as I can and on every machine I touch I will uninstall it and install PDF X-change viewer. On Win 7 x64 in my Dopus I have PDF thumbnails I have previews in Outlook 2010 as well and am pretty sure I never installed any 3rd party addin for it.
I'd like to second what dmorgan said
I use the same PDF viewer and it is much faster in all possible ways. Plus it adds nice shell info columns, so I don't miss Acrobat
PDF XChange Viewer is freeware.
I'm using DOpus 10.5.2.0 on an XP Pro machine. Until recently, PDF thumbnails displayed normally. However, now they do not. I'd like to get the thumbnails back, but don't know what made them disappear. I have Adobe Reader 11.0.3 installed on this system. I also have Nitro Pro PDF 8.5.0.26 installed.
Recently I was on vacation on Cape Cod and took my ancient 12 year old Dell laptop with me. It's also an XP machine and it also has both DOpus and Nitro Pro installed, although I'm not sure which version of Nitro Pro because the laptop finally died while on this trip. (The BIOS died. I've taken the hard drive out, but not explored it. All new data had been saved to a thumb drive while on this trip, so I'm not really worried about fixing the old laptop.) However, while it was alive, all of the PDF files displayed thumbnails normally in DOpus.
Any ideas about why the PDF thumbnails suddenly stopped working and how I can get them back?
One of the few good things about ancient 32-bit systems.
The most recent version of Adobe Reader from Adobe is the same version that is presently installed on this system. I tried downloading a new copy from Adobe's site using both Firefox and IE. Both browsers responded with an error message and aborted the download, although cookies were not blocked on either system. So I tried installing directly from Adobe, rather than downloading. This worked up to a point, when a new message appeared saying the version I was trying to install was already installed. As with the download attempts, the installation attempt was automatically aborted.
As I had work to do using Adobe Reader and the Reader program was working fine, I decided to continue working and wait 'til the weekend to uninstall and reinstall Adobe Reader.
Then this afternoon DOpus crashed while I was working in a folder and shut down the program. DOpus automatically restarted. To my surprise, when it reopened all of the PDF thumbnails were fully visible and functioning normally again.
I don't know what happened, but now I can enjoy my weekend.
See what happens. If it works then it works, if not then it's worth trying and uninstall + reinstall of Adobe Reader (or a repair install if it has one).
I've since built up a new system and installed Windows 8.1 64-bit. I now have all of the PDF thumbnail issues others have been having. However, I have a semi cure and am hoping you can help make it a full cure.
On my old system I have been using Nitro PDF Pro for years, and I installed the latest version on my new 64-bit system. Although the program is still 32-bit, it generates thumbnails. To do this, in Nitro you to go to File>Open, which brings up a window with a folder tree on the left side and the folder's contents on the right. Clicking through the display options and selecting thumbnails displays the folder's contents in thumbnails. Not all that hard to understand, as one of the options of PDF files is to display thumbnails of the individual pages to the side of the document. What surprised me was that subsequently when I open DO, navigate to that folder, and change the view to thumbnails, all of the PDF files are displayed as proper thumbnails.
Only in that folder, though. In other folders there are no PDF thumbnails.
For another folder in Nitro, I set display to thumbnails and opened that folder in DO. I was surprised to find that not all of the PDF files had thumbnails. The last ones listed in the folder did not. I went back to Nitro and scrolled down the folder. The folders that were listed below the window display had not yet had thumbnails generated. Once Nitro generated thumbnails for those files, they were displayed in DO as well.
The thumbnails remain displayable even after Nitro is shut down.
It would seem that I have to open every folder for which I want PDF thumbnails displayed in Niro first. A long process, and obviously PDF files added later would not have thumbnails until I viewed the folder again in Nitro.
Is there a way to tell DO to use Nitro to generate thumbnails for PDF files?
