Issues fixed

Installing from CD on Vista and later

If you have problems, follow these steps:

CD on Vista and later^{[citation needed]}
Open "Computer" in the Start menu, right-click on the CD and select Explore. Run the installer program (the application that has Install at the beginning of the name).

Installer/game not launching correctly on newer Macs

Renaming to .app^{[citation needed]}
Blades of Avernum might not run properly on newer Macintoshes and trying to run the game/installer will give an error. This problem is caused by the name of the program not ending in .app. To fix the problem, change the name of the program so it ends in .app. If you are trying to run an installer from a CD, copy it to your machine, change the name so that it ends in .app, and run it.

Screen Freeze Bug On OS X

Shift-R^[1]
In recent versions of OS X, game's graphics might occasionally freeze for a small number of users. The game is playing in the background and sound effects are still happening, but the graphics are no longer refreshed on the screen. Solution: When the screen freezes, type Shift-R. This should enable you to resume the game normally. Upgrade to the newest version of the game.

Crash on Steam version

You can ask for a copy of Avernum IV if you have bought the game to the developer.

Slowdown on Windows

Slowdown^{[citation needed]}

There is a rare problem in newer Windows machines where the game plays extremely slowly. This appears to be cause by an interaction between Avernum 4 and a driver or other piece of software we haven't identified.

If you encounter this problem, reboot your machine and run Avernum 4 before running any other programs. If you have any music software running in the background, quit it before running the game. There is a good chance that this will help the problem.

Also, some people have reported having the problem on systems with multiple monitors. Try deactivating the second monitor and see if the problem persists. If this solved the problem, please E-mail us and let us know. It will help greatly with finding a solution.

Unable to open sound channels

Audio MIDI Setup^{[citation needed]}
Open the Applications folder. Open the Utilities folder. In this folder, run "Audio MIDI Setup" Under Audio Output, change the Format to 44100.0 Hz.

Other information

Backing up the registration key

If you want to play the game with the same key, transfer the "avernum.dat" file (Windows) or "Avernum Prefs" (OS X) located in the Preferences folder (inside the Systems folder on your hard drive) to a safe place.

Requesting a new key

If you have lost a registration key, go to this page or e-mail the developer to get one.^[2] Be sure to add:

The game title
The complete mailing address you ordered the game under (NOT an E-mail address)
The new game and/or editor registration number the game is giving you now
Windows or Macintosh version
