You can't open the application "..." because it is not supported on this type of Mac.

I migrated all files from OS 10.7 to OS 10.8 through time machine. However, I always see error packages like the following if I want to run some .pkg files.

You can't open the application "..." because it is not supported on this type of Mac.

But when I switch to a different account, then the .pkg files can be run. Therefore, I think that there might be something wrong with my account configuration files. But I don't know which one. Does anybody which one might cause the problem and how to fix it? Thanks!
