Hello there 
I have been having this problem for a little under a year now and it's really starting to bug me!
Whenever I download something new off of the internet (new versions of programmes) it will complete in the download window on my Mac, then when I go to open it to install it, it appears to try and open in my dock then closes it immediately like it just can't open it, you can see the icon start to appear then it just stops pretty much straight away.
I have just tried to install itunes 9.0.2 and it did it and it has also done it on the many occasions I have tried to install the new flash so I can listen to music on myspace.
This is a screen shot of what appears on my desktop when the download has completed:
And this is a screen shot of the window I get when I open the iTunes9.0.2.dmg icon:
My Macbook is 2 years old and runs on Mac OS X Version 10.4.11.
If anyone can help me I would really appreciate it, I'm worried I won't ever be able to get new versions of stuff ever again!
