.dmg files

[onebrick]

I had a hard drive crash -- Apple replaced it BUT since then I cannot download
and open .dmg files -- example -- www.pando.com and firefox. They download to the desktop but when i click on them to open nothing happens.
I called Apple Care and they have no idea what's the problem. Any suggestions?

If you Ctrl-click on a .dmg file, what is selected to open it?
My system uses "DiskImageMounter."

also try disk utility(HD/applications folder/utilities folder) to open the dmg file.

I was having the same problem. I tried repairing the permissions and the disk, but that didn't seem to fix it. I reset the PRAM and now .dmg files open again.
