Firefox 8.0.1-4.dmg - downloads - could not be opened. Quick Time Layer cannot open files in the "Disk Image" Format - What do I need to do?

I get the above message when I try to download Firefox updates.

That is a disk image file and you can't open that in an application.
<br />
Make sure that Firefox gets installed properly.<br />
Open the Firefox disk image (DMG) file with a double-click if necessary and drag the Firefox program to the application folder on your hard drive.<br />
You shouldn't double-click the Firefox application to run it from the disk image, but drag it out of the DMG folder instead.

They screwed up the first Flashback removal tool very badly, locking several users out of their accounts permanently. It took a day or so for them to react and post a revised tool, but the damage had been done.
They are one of several formerly PC only vendors who rushed to the Mac front back in the spring after the Flashback scare. I would advise giving all of those folks time to prove they really understand OS X before installing it on any of my Macs. There are several others who have proven themselves.
Since you are running what I assume to be a fully up-to-date OS X 10.6.8 you are not vulnerable to any currently known malware capable of impacting OS X or other Mac software. That's no guarantee there won't be something new show up tomorrow, but the chances of any commercial anti-malware software catching it before Apple can react is pretty slim, IMHO.
Now if you are concerned about Windows malware, that's a different story.

My FaceTime seemed not working and keep telling me The document "IMG_3054.JPG" could not be opened. FaceTime cannot open files in the "JPEG image" format. I clicked OK but it pop-up again. So that I can't turn off my computer at all.

I tried to clike OK but this worning message keeping pop-up and I can not quit FaceTime. So that I can't turnoff or restart my computer.

The next time that happens, try this keyboard shortcut.
Command + Option + Esc
That way you can "force quit" the Facetime App.

In trying to update I received this message: Firefox 3.6.3(2).dmg.part could not be saved, because the source file could not be read.

In trying to download an update I first received: "There were problems checking for, downloading, or installing this update. Firefox could not be updated because: No data was received (please try again)" It also gave a link to download manually. When I tried from the Firefox website I got: /Users/(deleted for privacy)/Desktop/Firefox 3.6.3(2).dmg.part could not be saved, because the source file could not be read.
Try again later, or contact the server administrator. I tried this 3 times.
== This happened ==
Not sure how often
== Mon around 11 am, central time, May 17, 2010

I have tried downloading the file several times and get the same message: "No data received." I have no other system problems, I navigate well to other sites, but I'm unable to download this upgrade. Any suggestions?

If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

Hi,
Firstly make sure you save it to your hard disk, and then run setup from there.
If it doesn't help, you may also try to unregister Windows Installer, and then reregister Windows Installer and check if it helps. To do this, follow these steps:
1. Press Windows Key + R
2. In the "run" box, type "msiexec /unreg", and then press ENTER.
3. Press Windows Key + R
4. In the "run" box, type "msiexec /regserver", and then press ENTER.
Besides that, You could try to create a new user to download and install the application.

I can't restore my iPhone 4S the iPhone " " could not be restored. This device isn't eligible for the requested build. What I have to do?

You can also take a look at this information from this support document: http://support.apple.com/kb/TS3694
This device is not eligible for the requested build (Also sometimes displayed as an "error 3194")
Update to the latest version of iTunes.
Third-party security software or router security settings can also cause this issue. To resolve this, follow Troubleshooting security software issues.
Downgrading to a previous version of iOS is not supported. If you have installed software to perform unauthorized modifications to your iOS device, that software may have redirected connections to the update server (gs.apple.com) within the Hosts file. Uninstall the unauthorized modification software from the computer.
Edit out the "gs.apple.com" redirect from your hosts file, and then restart the computer for the host file changes to take affect. For steps to edit the Hosts file and allow iTunes to communicate with the update server, see iTunes: Troubleshooting iTunes Store on your computer, iPhone, iPad, or iPod—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > The hosts file may also be blocking the iTunes Store. If you do not uninstall the unauthorized modification software prior to editing the hosts file, that software may automatically modify the hosts file again on restart.
Avoid using an older or modified .ipsw file. Try moving the current .ipsw file (see Advanced Steps > Rename, move, or delete the iOS software file (.ipsw) below for file locations), or try restoring in a new user to ensure that iTunes downloads a new .ipsw.

I have my photos in iPhoto but my iPhoto library is empty.When clicked message reads could not be opened image capture cannot open files in the photo library format. How do I get my photos back into my library?

When what is clicked?
There are 9 different versions of iPhoto and they run on 9 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS. So to get help you need to give as much information as you can. Include things like:
- What version of iPhoto.
- What version of the Operating System.
- Details. As full a description of the problem as you can. For example, if you have a problem with exporting, then explain by describing how you are trying to export, and so on.
- History: Is this going on long? Has anything been installed or deleted? - Are there error messages?
- What steps have you tried already to solve the issue.
- Anything unusual about your set up? Or how you use iPhoto?
Anything else you can think of that might help someone understand the problem you have.

HT3350 what can you do when you get this warning? "Scouting Book Collection Index" could not be handled because Numbers cannot open files in the "Numbers Document" format.

“Scouting Book Collection Index” could not be handled because Numbers cannot open files in the “Numbers Document” format.

This file was created in 2002 in MSword but this had been forgotten.
When I went to open it.... (MSword) was not a program option on my laptop. For some reason, I assumed that either Pages or Numbers wouild open the file. How the file was created was forgotten and had no file Info, but I new that it was a table of valuable information.
The warning threw me off, because it led me to believe that it was a Numbers file. which Numbers would not open. A paradox.
I took the file to a laptop in OSXpanther with MSoffice and it opened in MSword. Problem Solved.
Thank you for your help.
