Somebody here should know something about it. There are some applications on osx that crash when I try to run them. I download trial versions from several companies. Some of them are well-known, like zend studio, or sorenson squeeze etc. I download. I open dmg. I double click the .app. Osx tells me that the application crash. I don't know why. New versions of applications, what cause the crash? I have one suspicion about the way I upgraded from tiger to leopard. I think I used 'archive-install' option. But it should be ok I think. We dont talk about rubbish microsoft windows here! After all 'archive-install' is a normal option on leopard installation disk. Most of my applications run smooth. Photoshop, ms word, many others. No problem at all. It seems that something strange happens to my system. I don't know why new programs crash on my osx. Can you please help me.
