Yes indeed, see here.

Thanks, that's very interesting as I was having some problems accessing Instagram earlier on today intermittently, and that's probably why. It doesn't explain the problems with the videos displaying though, as they have carried on working in other browsers, just not on Firefox!

Absolutely, Classic Shell (now Open-Shell) is one of the greatest programs ever released IMO, and it's free! It was the only thing that made Windows 8/8.1 usable for me, and even improves the Windows 10 UI enormously. Its writer cannot have enough praise from me!

Yes, my normal installation of Google Chrome 49 (the last that works on XP of course) displays the Instagram videos fine, as it always did! Even more strangely, if I look at the Instagram "Page Info" on the right click in Firefox 52, on the media tab the videos are still listed there, and if I click on them they appear in the preview pane below, and can even be played there. They just no longer appear on the actual Instagram pages! This is very strange indeed, as they obviously aren't actually blocked, they are just not displaying any more on the pages as they should do.

Just tried changing the user agent, but absolutely no difference I'm afraid. Facebook videos still seem fine with - Mozilla/5.0 (Windows NT 6.1; WOW64; rv:57.0) Gecko/20100101 Firefox/57.0 Should I change that to the later one? Addition: I've just tried with Google Chrome 49, and Otter, and the Instagram videos still work fine there! Very strange, as Google Chrome 49 is far more out of date than Firefox 52ESR!

All fine here (touch wood!)

Thanks everyone, so Instagram presumably changed something yesterday to cause this? The videos were working fine for me up until then. They never played automatically like they do on my phone, I always had to manually start them by clicking on the white play icon in the centre of them, but it's like that on Firefox 65 on Windows 10 as well, so I guess that's a "feature" of the desktop browser version of Instagram. Very annoying, I wonder if there is a workaround for this like there is with Facebook, where the HTML videos do work if you have the Primetime plugin installed.

I've just noticed today that videos don't now seem to be appearing on Instagram pages with Firefox ESR 52.9.0. There isn't even a placeholder, they are completely missing, all that's there of the posts is the text that should be beneath the video frame! Static images are still displaying fine. Is anyone else seeing this? They were fine yesterday! The videos are still fine in Firefox 65 on Windows 10 needless to say. I've tried spoofing the browser user agent using an extension, which I already have to do to get Facebook HTML5 videos to work, but none of the ones I've tried make any difference on Instagram.

Yes, me too. Still no replacement for MSO.DLL, KB4462174 still hidden. I assume Office 2010 is supported until next year, as it's usually ten years of support. I wonder if we'll ever see a fix for this?

Rather late in the day to this, and I'm sure this has probably already been tried, but if I had this issue I would try uninstalling everything in Device Manager, ignoring the reboot notices of course, and then see if the machine will boot in Safe Mode. If it does, then it must be a driver problem and then it's just (ha-ha!) a matter or narrowing down which one it is. When you reboot normally the OS should put all the devices back again as you haven't actually removed the driver software from the machine (there's an option to do that on uninstall on later versions of Windows, but not on XP). It may actually put them back differently, which might also affect the problem.

Thanks @jaclaz. It may not be difficult for you, but it is for me! I'll leave things be for now, but I would be very interested if @rloewcan write a program that will correct the issue without reformatting. If he does I will certainly buy it and use it.

This is all way over my head I'm afraid! My NTFS drives were formatted by Windows 10, so presumably there's no problem there. My FAT32 drives were all formatted by Windows 98SE. Is there therefore a problem I need to address with the FAT32 drives, and if there is would any solution mean I would have to reformat them? That I'm not keen on doing of course, but if it's going to mitigate against problems in the future, I'm willing to consider it. I do need to format quite large drives with FAT32, but I'm pretty sure that Partition Wizard can do this, presumably with correct alignment. I said "Partition Magic" earlier, when I actually meant "Partition Wizard". Sorry if that's caused any confusion!

The free version of Partition Wizard, which I've used for many years, has an "align" function, which I'm pretty sure I have used in the past on my FAT32 drives, both SSDs and conventional drives. Will that actually fix this issue where I've partitioned and formatted drives using Windows 98 Fdisk? The reason I used that method was because the size of FAT32 partition you can create with Windows XP and later is quite limited.

So is that a problem I should worry about? It's been like it for several years now and there doesn't seem to be any symptoms of things not being right.

I'm not sure why you would need to format using Windows 7. I have Windows XP and Windows 98SE running on a partitioned SSD and I formatted it (FAT32 of course) using Windows 98SE as I've always done! I did try the Naraeon TRIM program mentioned earlier in the thread, but it doesn't actually support my SSDs, which are all Seagate ones. It may be OK with yours though. Although I have Windows 10 on the machine as well, it won't TRIM FAT32 volumes, so I actually trim the FAT32 SSDs using RLoew's DOS TRIM tool!

I got four this morning, KB2589339, KB4462229, KB4461626, and KB4018363. Office is still working, but KB4462174 is still being shown as a hidden critical update. I guess that means that the faulty MSO.DLL hasn't been replaced with a working one. We'll see what happens next Tuesday!

I'm still puzzled here, what exactly is Windows Photo Viewer/Windows Picture Viewer? I don't have anything called either of those names on either of my XP installations. Is it a built-in Microsoft program?

I use Windows Search 4.0 on both my XP installations, with the traditional Search Companion re-enabled as I prefer it to the Windows Search 4.0 one, and yes, on one of them Rover still struts his stuff!

It's version 7.1.0.9, which was the very last version released by Qualcomm. If you put the Eudora folder from the zip file into your Program Files folder, does it not run?

Thanks @jumper I assume you mean the lite version of Eudora? If so, did you download my full Eudora installation here? That should be the whole program folder, which should work, including all the plugins. I have of course removed all my mailboxes and account information. Cheers, Dave.

Hi guys. Just wondering, is anyone still looking into this, or has everyone decided that it's actually unfixable? Just as an aside, there is a delay displaying those Sky e-mails with Eudora when running it on Windows 10, but it's a matter of a few seconds, not the 10 seconds or so that happens in XP. Cheers, Dave.

Yes, all fine for me too, apart from the ongoing Office 2010 problem of course!

Which Photo Viewer is now broken? Windows Live Photo Gallery is still working for me, if that's what you meant.

I was quite seriously told by someone to get off a forum because I was a danger to everyone on the internet because I was still using XP, and that was four years ago!

Thanks again guys! I really appreciate you all sticking with this. Here are the two images as I promised. This is how a message from Sky looks in the "Microsoft Viewer" when it finally displays after a long delay - And this is how the same message looks in Eudora's own built-in viewer, which displays it instantly - As I said earlier, if any fix or workaround results in it still looking like the second image, I will not worry one bit, as it's still perfectly readable! It's the delay that I really want to lose so I don't have to keep switching viewing modes on Eudora all the time. The Marks and Spencer e-mails are a worse problem as they look an awful scrambled mess in the Eudora viewer, but I don't get that many of them. Here too is the installation file for the Bugscreen Eudora plugin. This is the actual file that I found and downloaded to install the plugin when I was collecting up as many legacy Eudora plugins as I could find a few years ago! Cheers, Dave.
