Re: paramErr from LaunchApplication?

It sounds like this code works for an application located on one disk image, but fails for the same application located on a different disk image.

It could be a "FSSpecs aren't valid across processes in OS X" problem. Have you tried using LSOpenFSRef() (in LaunchServices.h) instead of LaunchApplication()? I guess you'd also want to make sure that you have read / write / execute permission on each disk image.

OK, I am *totally* baffled on this one!

Platform: Mac OS X 10.2.6, 768MB RAM

Wrinkle: Launching applications from different disk images.

Code:

if (isMacApplication(&theAppFSSpec))
{
LaunchParamBlockRec pb;

pb.launchAppSpec = &theAppFSSpec;
pb.launchAppParameters = NULL;
pb.launchBlockID = extendedBlock;
pb.launchEPBLength = extendedBlockLen;
pb.launchFileFlags = 0;
pb.launchControlFlags = launchContinue | launchNoFileFlags |
launchUseMinimum;

err = LaunchApplication(&pb);

if (err == noErr)
{
// Do stuff while running
}
}

For some reason, the first LaunchApplication succeeds, but the *second*
LaunchApplication call returns paramErr.

What am I missing here?
