This problem would occur when user do not have write access to "~/.adobe/Acrobat/9.0/Preferences/reader_prefs". You can verify this by doing

`ls -ltr ~/.adobe/Acrobat/9.0/Preferences/reader_prefs` .

Scenario when this might happen is when you try launching reader by doing `sudo acroread` , and after that launching it as normal user by just typing acroread.

To solve this problem, you need to delete or take backup of your reader_prefs file, by doing "sudo rm -rf ~/.adobe/Acrobat/9.0/Preferences/reader_prefs" or use mv command to move it elsewhere ( for backup).

Then launch reader by just typing acroread.

If you really wish to use sudo command to launch reader, then use sudo -H acroread (i.e. sudo with -H option).

Thanks,
