"An error occured inside a plug-in contianed on this page"

I was having the same problem, with browser Internet Explorer. I decided to try installing a different browser. So I installed Firefox, and had it transfer all my favorites, etc. from Internet Explorer. Then, within Firefox, the QuickTime plug in magically worked. I did not even have to install the plug in. I hope this helps.

Same problem. Trying to watch http://www.pbs.org/wgbh/nova/elegant/program.html . Using IE Version 7 under Vista. Probably an IE problem based on the other reply.

I'm having the same problem. It started after I installed the latest update. I've uninstalled and reinstalled the program several times to no avail.

I and my colleagues are getting the same problem. On IE I can play one QT file, but if I try to play a second one I get this message, and the only resort is to close IE and start again. But no problem with Firefox.

I am having the same problem after just installing QT 7.4 and I tried to uninstall and reinstall last night, but it did not work. Hope that a solution is posted so I don't have to go down to an older version.

We have created thousands of panoramic images using QTVR. Every display page directs viewers to Apple.com to download the latest QuickTime. I was about to post a 15 pano site for a chamber of commerce client and noticed that Apple had posted QT 7.4. I installed the new software and in testing, discovered that all our panos are broken. We would get "The plug in did not initialize properly".

I contacted friends in the IVRPA community and other professional VR firms and most are experiencing this issue, but on a very intermittant level.
In testing I even found that Apple's main site would crash intermitantly. Please go to www.apple.com and open the airbook ad. With QuickTime 7.4 and IE 7.0.5730.11 We have been getting intermitant lock ups. Some times you can view the Air Book ad, sometimes the ad locks up.

The same circumstances have appeared with museum sites using QT. Our own gallery failed to load this morning. www.buzz-card.com/gallery.html Two questions: are others finding similar problems? Is Apple concerned?

Just as others have said , we built a business around QTVR. The software had been fabulous in the past. However the 7.4 glitches are a serious and un-expected problem. Our clients will not accept a solution which works "sometimes".

I just tried a web site that had been having the problem and i got QT to work on the first video and then got the same error message... plug-ins... blah, blah, blah again. Problem is not fixed yet.

Having the same problem. What is IE7? Are there any 'patches' for the plugin - not that I'd know how to install it, but my local computer tech mentioned it. Anyone know? Is IE7 a patch?

I am having the same issues here. I do videos for a realty company and they are all in quicktime. The problem is definitely between IE7 & QuickTime 7.4. I've tested it with IE7 & 7.3 and it works fine. So far the only work around is using Firefox or downloading the 7.3 QuickTime version from Apple's site here. I've tried calling the "Contact Us" support # and they don't have any phone support, just this forum....THATS IT!! I'm a little ticked off on this, mostly because I don't know what to tell the clients about fixing this problem besides making them go out of their way to view the videos. If anyone has any ideas or finds anything, please post ASAP!! Thanks!!

I'm having the same problem after installing QT 7.4 on XP Pro and IE 7. When I first open IE 7 and click a QT video it will play but if I try and view another QT video I then get the "An error occured inside a plug-in contained on this page". I can close and restart IE 7 and QT will again let me view the first video I click on but that all. The error pops up again each time after that.

Knowing I didn't have this problem with QT 7.3 I install it over QT 7.4 just fine but I still have the same problem. QT 7.4 has really goofed things up.

I hope someone or Apple comes up with a solution fast, it's driving me crazy.

The same thing is happening to me. How can you get help with this thing? This is one MORE reason I don't get a MAC. And I am VERY glad I didn't get the QuickTime Pro -- no one helps you. I am taking a class online and need QuickTime to watch the lessons -- it's for my job. I'm having to actually reboot after each video lesson to get another one to play. It plays once, then I get the "error occured inside a plugin on this page' message. Doesn't anyone from Apple monitor these boards and see that they have really messed up?
