If the idea is to get an array of the values:

int i, count;
NSMutableArray * tMutableArray;

count = [software count];

tMutableArray=[NSMutableArray arrayWithCapcity:count];

for (i = 0; i < count; i++)
{
   NSDictionary * tDictionary=[software objectAtIndex:i];
    
   [tMutableArray addObject:[tDictionary objectForKey:@"install"]];
}

NSLog(@"%@", tMutableArray);
