Installing software from one of these requires you to mount the image and move its contents to your computer’s “Applications” directory. Some Macs aren't able to recognize the DMG files created as a backup. Here's how to fix the issue. What to Do If Your DMG File Is Not Recognized on Your Mac 2.

I have QQ messenger (Just a messenger I use with my friends) on my Macbook Pro.
It had some kind of problem so I deleted it from my applications and dock into the trash.
I emptied the trash because I thought that If I deleted it I could just re-install Qq messenger and the problem would be gone.
I downloaded it and when I went to open it, this popped up: http://i950.photobucket.com/albums/ad343/iKawaiiChan/ScreenShot2011-09-10at81456PM.png
I'm not sure what to do since I'm not good with this tech stuff.
I'm not really sure where to put this question either so I just put it here.
Please help.

Open DMG File

DMG is used for disk image files on Macintosh computers running Mac OS X. This file extension replaces the older file extension IMG which was discontinued during the release of later series of Mac operating systems. You can open DMG file on Mac, Linux, and Windows operating systems but it will require additional software to be installed on Windows. Note that on Windows and Linux you cannot open every DMG file, since there are certain software limitations on DMG format variation.

DMG files are used by Apple for software distribution over the internet. These files provide features such as compression and password protection which are not common to other forms of software distribution file formats. DMG files are native to Mac OS X and are structured according to Universal Disk Image Format (UDIF) and the New Disk Image Format (NDIF). They can be accessed through the Mac OS Finder application by either launching the DMG file or mounting it as a drive.

Aside from the Finder application, you can open DMG files through Apple Disk Utility, Roxio Toast, and Dare to be Creative iArchiver for Mac platform. On the other hand, additional applications such Acute Systems TransMac, DMG2IMG, and DMG2ISO can be installed on Windows to fully support the files.
