An easier way may be to get NSWorkspace to do the work for you using
the "openFile:" message.

Dennis,
You need to set the launch path of the executable within your NSTask
- currently you're passing /usr/bin/open as an argument to nothing.
There are two ways to do this: firstly, using the same logic you've
got below, you can have the launch path be a shell and pass /usr/bin/
open as an argument to the shell; alternatively, make /usr/bin/open
the launch executable.
Option one, notice the added "-c" switch to the shell:
[task setLaunchPath: @"/bin/tcsh"];
[task setArguments: [NSArray arrayWithObjects: @"-c", @"/usr/bin/
open", path, nil]];
Option two:
[task setLaunchPath: @"/usr/bin/open"];
[task setArguments: [NSArray arrayWithObjects: path, nil]];
Caveat: This is from memory, but it shouldn't be too far off.

I'm trying to distribute an installer within my own application
bundle in the resources directory and run it from my application.
When I try to run it from the debugger I get the error "launch path
not accessible". However, if I then use the terminal to run the
command by hand using the same path it works.
Anyone have any idea why it fails to run it from the application?
Code in my application:
NSTask* task = [[NSTask alloc] init];
NSString* path = [[NSBundle mainBundle]
pathForResource:@"FTDIUSBSerialDriver" ofType:@"pkg"];
NSLog(path);
[task setArguments: [NSArray arrayWithObjects: @"/usr/bin/open",
path, nil]];
[task launch];
Output from the debugger when it fails:
