Sorry--I wish I could be more helpful, but I'm not much of a programmer. More of a tinkerer.
That's fine. Your logs helped, and ngld filled in the gaps.
Also, I double-checked the files that the installer uses... on Linux, the innoextract distributable is a script that launches a binary, but on OSX it's just the binary. Per ngld's answer to #2, that would mean it probably wouldn't work on OSX in any case.
Here is another build that you can try. I changed the strategy for launching external applications on non-Windows systems:http://staff.hard-light.net/goober5000/temp/FreeSpaceOpenInstaller.jar
FYI the following files did not download as their mirrors appear to be down:
Yes, several people have reported this. I consulted with achtung and updated a few of the mirror links. Try again.
That would require integrating BitTorrent into the installer, which is another project by itself. It's not going to happen in the foreseeable future.
I had some similar problems when testing just now. Interestingly some files seem to download OK when using wget, they just don't work in the installer.
Weird. Some of the problems are due to mirrors that are down, but others are due to HTTP 403 Forbidden. I wonder if some ISPs aren't taking kindly to access by the installer. Try running another test, now that it's been a week and the mirrors have been updated.
I've set up a pretty simple mirror monitor.
Mods with a cross in front of their name can't be installed because all mirrors for one or more files are offline.
If you click on a mod's title it will show you which files are offline. The page is updated every hour.
Well that is pretty cool. Thanks.
Also what is different in the GOG version versus like the GOTY edition that prevents the installer from working with it? Just curious.
As niffiwan stated, it's merely that the files on the install discs are in a different format. One would have to write an extractor for the CD file format in order to add that functionality to the installer. But as chief1983 stated, if you can install FreeSpace 2 on another machine and then copy the files to your gaming machine, that should be sufficient to use the FSO Installer to install the other mods.
Even if I can't use this for now, thanks for all the work you have put in, to create a simple, one stop/step solution to installing the FSO and all the great mods that showed this was a game that was not only ahead of its time when designed, but a game that is a shame no one has picked it back up or even tried to do a kickstarter/greenlight, after all how many more Zombie games do we need, compared to Space Sims (keeping fingers crossed on Star Citizen, but don't want to get my hopes up, just in case it doesn't work out, also the Eve and Elite projects that incorporate the Oculus - promises of VR have been around for a long time so another of those lets see it come to fruition and the support by the developers before jumping in).
But again thanks for time you put in and hopefully the goty edition can use your installer. If not guess will have to wait till you release 2.2 or 2.3.
You're welcome, and thanks for the kind words.
