HI,

This entry may be useless for people who are using UBUNTU for a while now. But still i am writing this for the newbies

you can assume these files to be like .exe in linux flavour. To install a run file follow the steps

1) Open terminal window ( Applications>Accessories>terminal)

2) Browse to the run file which you want to install

3) Type ./nameoffile.run

4) It may give you error that it requires root credentials, then please type sudo .nameofile.run

That should solve the purpose

cheers !!

Realin !
