After nearly five years, we've come to the end of our last D&D 4e campaign. Since those of us using Hero Lab already had the Authoring Kit for Savage Worlds, we started using Hero Lab for our 4e characters. Over the years, we've done a fair amount of work on the 4e files. We didn't expect any more "official" updates, and we were doing these for ourselves not really expecting our work to be used outside our own group; that means that rather than doing things in discrete files to be added to the downloaded system files like we would have for Pathfinder or Savage Worlds we actually edited our copy of the game files. Nonetheless, there's been some outside interest in our work, so I've put a copy of our modified files up for download for anyone who wants to use or just examine them. Sorry that I don't have a proper fix list, but it was never a proper project.
Because it's a modification of the official files, you have to have the official files installed first, and copy our files over the initial ones.
Here's the procedure:
1) Download the Zip archive
here.
2) Open the Hero Lab 4e Game System Data Folder. The default location in Windows is C:\ProgramData\Hero Lab\data\4e but in any case you can get to it from within the Hero Lab for 4e menu at Tools > Explore Folders > Game System Data Folders
3) With Hero Lab closed, unzip the archive to the Game System Data Folder, overwriting any duplicate files.
4) Now when you open Hero Lab 4e, you should be using our files.
Do realize that although we fixed a ton of bugs, there are undoubtedly many more that we never ran across. Please don't send us bug reports; we're done with 4e. If anyone wants to use our files as the basis of their own efforts, more power to you.
