using install all option

im seem to be having a problem using the install all option i keep getting this

Fatal error: Maximum execution time of 30 seconds exceeded in
...../arcade/functions/tar.php on line 181

doing theme one at a time seems to work fine but man this is taking forever and i have a massive amount of games.

also I purchased some premium games i want to integrate into the arcade im sure there is a tutor somewhere if you could piont me there thanks....
