I have 12.04 installed on my laptop. I am the admin of the computer, but every time I try to change file permissions to access files or tick execute file as program then it just changes back quickly or unticks the box quickly.

I am really desperate! Please help.

How did you install Ubuntu and what is the path to the file you want to change permissions for? – jippie Nov 4 '12 at 18:49
I installed it from dvd. And the path to the file... can you explain it to me? – Harald Nov 4 '12 at 18:50

First try, from the command line:

chmod 777 file_name_here.txt

This will set everyone to access everything (a huge security risk) so only do it with one file.

If you get errors about a read only file system, then your file system is read only and that is another problem.
